Academic response to radical paper: fire him!

9:04 am

Fascist academia: A professor writes a paper suggesting that colonialism wasn’t all bad, and the academic world responds by calling for censorship, a boycott of the journal for publishing it, and demands that the professor be fired and blacklisted.

It appears from the academic responses to the paper, very carefully documented in the article, that none of the protesters bothered to read it. From their perspective, the professor dared say something that is simply not permitted, and therefore must be silenced and destroyed.

But then, how do you have an open marketplace of ideas if some ideas are “simply not permitted?” You don’t. This article illustrates the fascist culture that now permeates many academic fields, totally counter to the concepts of open debate, freedom, and individual liberty that western civilization is founded on.

Federal bureaucracy prevents satellite launch

8:33 am

We’re here to help you! A suite of 8 private commercial cubesats that the Air Force had agreed to launch as secondary payloads on the August 26 launch of a Minotaur rocket were blocked from launch by FAA bureaucracy.

The “interagency partner” that appeared to raise objections was the Federal Aviation Administration, which issued the launch license for the mission. “The Federal Aviation Administration (FAA) did not approve Orbital ATK’s request for a license modification to include commercial cubesats on the upcoming ORS-5 launch mission,” Guthrie said. “As a result, Orbital ATK decided not to include commercial cubesats on the launch.”

Asked if the FAA placed any conditions or restrictions on the ORS-5 mission launched on the Minotaur 4, agency spokesman Hank Price said the FAA issued Orbital ATK a license Feb. 10 to launch government payloads on the Minotaur 4 from Cape Canaveral. The launch license contains any and all conditions on the license, Price said, and the FAA does not comment on the “existence or status of launch license applications or modifications until the FAA makes a final decision regarding those requests.”

Industry sources believe the FAA never formally rejected a proposed license modification for the cubesats because it did not go through the official process, but it was informally clear that the agency would have rejected such a modification had it been formally submitted.

Spire officials are trying to figure out why there was any issue at all about commercial cubesats on this launch. “If Spire chose this launch in the place of another commercial offering, I would understand the industry’s concern about fair competition,” Barna said. “But no existing U.S. launch company or new entrant was offering a similar launch. The fundamental intent of the policy is to keep competition fair, and competition just wasn’t a factor here.”

Spire’s problems here demonstrates the difficulties smallsat companies have getting their satellites in orbit, which explains the emergence of a new smallsat rocket industry. The company’s difficulties also illustrates why the launch industry should always be opposed to giving too much regulatory power to government. In this case it really appears that the launch license was denied merely because the bureaucrats involved with approving it at the FAA simply didn’t want to bother dealing with it.

Middlebury College endorses heckler’s veto

10:12 pm

Another college no one should attend: Middlebury College, which saw violent protests when author Charles Murray gave a speech there, has established a new policy that will have them cancel any speaker “in cases of imminent and credible threat to the community that cannot be mitigated by revisions to the event plan.”

In other words, threaten violence against a speaker you disagree with, and you will successfully silence that speaker.

If this college believed in free speech, it would instead announce that it will immediately expel any student that threatens violence against anyone, and that it will do whatever is necessary to defend all speakers from violence. But the administration here doesn’t believe in free speech, so instead it invites violence against any unpopular speaker.

Carl Orff – O Fortuna from Carmina Burana

6:01 pm

An evening pause: The first half of this video is a great performance of Orff’s piece, written as the opening for Carmina Burana. The second half shows what I think is the closing scene from a staged performance, but has no sound and is unclear. Regardless, the first half is breath-taking, and includes English subtitles, which clearly places the context of this music in 1930s Germany.

Hat tip Wayne DeVette.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Brown University to offer segregated dinners to minorities

12:05 pm

Bigoted academia: Brown University has received a $30K grant to offer segregated dinners for blacks and Muslim women.

The university received a $30,000 grant from the Association of American Colleges and Universities, which represents liberal arts schools, to create a campus center whose mission is to “break down racial hierarchies and create a positive narrative about race in the community,” according to The Brown Daily Herald.

These grants, provided with the assistance of the Newman’s Own Foundation and W.K. Kellogg Foundation, will go towards hosting racially and religiously segregated “dinner discussion groups.” These discussions are being led by Brown University Chaplain Rev. Janet Cooper Nelson, who told The Daily that “one [group will be] for black students and the other [will be for] for Muslim women on campus.”

Democrats created and controlled the south when segregation ruled. They now control all of academia, so no one should be surprised if they are once again encouraging the idea there.

It all comes down to bigotry. Modern academia is obsessed with race, gender, and ethnicity. It is all they see when they look at a person. Thus, it shapes everything they do, including building segregated societies founded on racial and ethnic hate. And we can see the long term result of this in what is happening in St. Louis this week.

Navy removes top management in response to recent ship collisions

10:30 am

The Navy has removed the two top commanders of its largest operational force in response to the four recent incidents in the Pacific, involving three collisions and the ship’s grounding.

A third man has also requested retirement in order to “to step aside to allow for new leadership.”

The important question is whether the Navy is really instituting real management changes, or is simply rearranging the deck chairs on the Titanic. We shall see.

Oh no! Climate panel might include skeptics!

10:24 am

According to this Washington Post article, the Trump administration is considering naming some skeptical climate scientists to the EPA’s Science Advisory Board, something that the newspaper, the global warming crowd, and some EPA employees apparently consider a horrible taboo.

[T]he inclusion of a handful of climate contrarians has caused early concern among environmental groups and some employees at the agency. “We should be able to trust that those who serve the EPA are the all-stars in their fields and committed to public service,” said Michael Halpern, deputy director of the Center for Science and Democracy at the Union of Concerned Scientists. He said the upcoming round of appointments will test whether EPA Administrator Scott Pruitt is “remotely interested” in independent scientific advice. “He already has a parade of lobbyists and advisers providing him with the perspectives from oil, gas, and chemical companies. The Science Advisory Board is a check on political influence and can help the agency determine whether the special interests are telling it straight.”

What I find really hilarious in reading the article is its description of the various skeptics, almost all of which are qualified climate scientists. The article quotes their skeptical positions as if these positions are the insane ravings of an idiot, but everything these skeptics say is accurate and well documented by research over the past century. For example, there is this quote:

Another scientist, Craig Idso, is chairman of the Center for the Study of Carbon Dioxide and Global Change, where he has written that “the modern rise in the air’s CO2 content is providing a tremendous economic benefit to global crop production.”

Yet another scientist, Richard Keen, is a meteorologist and author who traveled with the Heartland Institute to Rome in 2015 for a “prebuttal” to Pope Francis’s encyclical on climate change. There, he argued that “in the past 18 years and how many months, four months, there has been no global warming.” Another candidate, Anthony Lupo, is an atmospheric sciences professor at the University of Missouri. In 2014, he told a local Missouri media outlet, KOMU 8, that “I think it is rash to put the climate change completely on the blame of humans.”

Idso is correct. Crops benefit from more carbon dioxide. This is common knowledge in the agricultural community, and has been amply proven by numerous studies.

Keen is also correct. In 2015 there had been no warming for almost two decades, and that pause only ceased last year because of El Nino, and appears now to have resumed.

Lupo is also correct. The theory that human behavior is the sole cause of global warming has not been proven, and if anything, the failure of every computer model based on this theory to predict the pause in rising temperatures suggests it is wrong.

If anything, the article illustrates the ignorance of its author and the newspaper, both of whom appear completely unaware of the actual uncertainties that exist in the climate field.

Cassini’s last image of Iapetus

10:05 am

Iapetus

The image on the right is a cropped and scaled up version of one of Cassini’s last images of Saturn’s moon, Iapetus.

The moon is unique in that its east and west hemispheres have completely opposite albedos, with one being very dark and the other very bright. It also has a very distinctive large crater, seen in this image. Scientists do not quite understand what causes the dichotomy, though they have models that partly explain it, partly from material being deposited on the moon’s leading hemisphere combined with the temperature differences at different latitudes.

The cause of the extreme brightness dichotomy on Iapetus is likely to be thermal segregation of water ice on a global scale. Thermal effects are usually expected to act latitudinally. That is, polar areas are colder than equatorial terrain in most cases due to the more oblique angle of the solar irradiation. Therefore, an additional process is required to explain the longitudinal difference as well. In one model, dark, reddish dust coming in from space and preferentially deposited on the leading side forms a small, but crucial difference between the leading and trailing hemispheres, which is sufficient to allow the thermal effect to evaporate the water ice on the leading side completely, but only marginally on the trailing side.

It was this moon’s strange dichotomy that had Arthur Clarke use it in 2001: A Space Odyssey. While Cassini’s images clearly prove that the brightness difference was not created by an alien civilization, as imagined by Clarke, those images have not really provided us a full explanation for its cause. The uncertainty of science marches on!

NASA’s international outreach continues

9:45 am

Barack Obama’s demand that NASA focus on teaching international students, especially Muslims, on how to get into space is continuing in the Trump administration.

The list of countries participating, available here, is not confined only to Muslim countries, and seems reasonable: Australia, Brazil, Israel, Jordan, Lithuania, Mexico, Portugal, South Africa, South Korea, Sweden, Trinidad & Tobago, the United Arab Emirates (UAE). At the same time, it is a reasonable question whether this should really one of NASA’s focuses.

Note one interesting detail. The European Space Agency is listed as one of these nations, but its program is presently on hold for reasons that are not explained.

ArianeGroup’s transition to Ariane 6 rocket

9:35 am

Link here. It appears that this transition not only includes replacing Ariane 5 with Ariane 6, but also the phase out of Russian Soyuz rockets by 2022. This loss of business is going to hurt Russia, as the government there desperately needs cash with the drop in oil prices.

The article also noted that ArianeGroup will charge two prices for Ariane 6, depending on configuration and payload, $85 million and $130 million per launch. These prices seem high, but because they likely cover the launch of two satellites, customers will be charged half these amounts, $40 million and $65 million, which is competitive in today’s market.

Will these prices be competitive in 2020s? I have my doubts. I estimate, based on news reports, that SpaceX is charging about $40 million today for a launch with a reused first stage, and $62 million for a launch with an entirely new rocket. Give them another five years of development and I expect those prices to drop significantly, especially as they shift to entirely reused first stages for almost every launch and begin to demonstrate a routine launch cadence of more than one launch per month.

This quote below explains how ArianeGroup really intends to stay alive in the launch market:

The price targets assume that European governments — the European Space Agency, the European Commission, Eumetsat and individual EU nations — agree to guarantee the equivalent of five Ariane 62 missions per year, plus at least two missions for the light-lift Vega rocket.

In other words, ArianeGroup really doesn’t wish to compete for business. It wants to use government coercion to force European space agencies and businesses to buy its product. They might get that, but the long term result will be a weak European presence in space, as everyone else finds cheaper and more efficient ways to do things.

Northrop Grumman to buy Orbital ATK

9:14 am

Capitalism in space: Aerospace giant Northrop Grumman has made a deal to acquire Orbital ATK for $9.2 billion.

This deal essentially allows Northrop Grumman to return as a player in the space industry. In recent years the company has not been visible in any major way in space. Orbital ATK gives it that.

At the same time, the flexibility and risk-taking seen at Orbital ATK that allowed them to build Antares and Cygnus for crew cargo will likely be more difficult as part of a giant corporation.

Evergreen settles lawsuit with banned professors

9:10 am

Evergreen State College has settled the lawsuit filed by two professors who, despite being threatened with physical harm by leftist protesters, were given no support or protection by the university.

Evergreen State College has settled a tort claim against it from embattled Professor Bret Weinstein and his wife, Professor Heather Heying, for $500,000, according to an email sent to faculty Friday evening.

“They have resigned from their faculty positions at Evergreen, effective today. The college will pay them a total of $450,000 and contribute an additional $50,000 toward their attorney fees,” according to the email, sent by John Carmichael, chief of staff and secretary to the board of trustees. “In making this agreement, the college admits no liability, and rejects the allegations made in the tort claim,” Carmichael wrote.

This settlement allows the university to deny that it looked the other way while thugs were making blatant threats of violence against these teachers, but the article provides ample evidence that the university continues to lie about its behavior, and is still unwilling to change.

[Carmichael’s] memo does not address how Weinstein was cornered in May in a campus building and blocked from leaving by rowdy student protesters furious he did not support the Day of Absence, videos of the incident show. Nor does it mention how Evergreen’s then-chief of police subsequently told Weinstein his safety on campus could not be guaranteed, and that it appeared student agitators were looking for him, forcing Weinstein to hold his class in a park.

According to the tort claim, at a campus meeting to address the racial unrest, Weinstein was also scared for his personal safety, that the meeting “became heated and threatening at times. There was only one exit, and it was completely blocked by protesters.” Campus officials had also instructed university police to attend the meeting unarmed, according to the claim. “Meanwhile, protest organizers announced that chairs and food in the room were for ‘people of color only.’ When they noticed there were sufficient chairs, organizers announced that white people had to sit in the back of the room. Administrators, including President Bridges, did nothing to prevent this,” the claim added.

There’s more, all of which demonstrates that no sane parent or high school student should consider Evergreen a college option.

India hopes to resume launches before December

8:53 am

Despite an August 31 launch failure, India is still planning to resume launches before December.

On Friday, Mr Kiran Kumar [head of ISRO] was optimistic that the workhorse rocket would resume flights within a couple of months. “We have identified what the problem is, and we are going through simulations to make sure what we are concluding, is what has exactly happened (during the unsuccessful flight on August 31). The committee, which has been set up to go through the report is having detailed discussions and the report will come out very soon. After the committee gives its final report, we will resume the launches by November-December,” he said, on the sidelines of silver jubilee celebrations of Antrix Corporation Ltd, the corporate arm of ISRO.

They might not meet this goal, but that they are trying to resume launches in less than four months indicates that they are emulating the private sector and not most typical government agencies like NASA in this matter. Both NASA and ISRO have in the past sometimes taken years to recover from a launch failure. After SpaceX’s launchpad explosion in September 2016 they vowed to launch in less than four months, and managed to do it in five months. That ISRO is now trying to do the same indicates that the competition has forced them to up their game.

The Worst Part of Losing Cassini Is That It Has No Replacement

8:45 am

Link here. This article is an honest review of the current lack of concrete plans by anyone to send a new probe to Saturn. While there are some tentative missions in the works, nothing is certain.

[I]f looking back on Cassini’s major discoveries at Saturn, Titan, and Enceladus have left you thirsty for more, we have some bad news: That thirst is going to go unquenched for a while. Talks of Uranus and Neptune missions are tentative at best. The best hope for Saturn now comes from NASA’s New Frontiers program, which looks for excellent medium-cost missions has spawned spacecraft including Jupiter’s Juno and Pluto’s New Horizons. This round of New Frontiers missions must launch by 2024, and there are two Enceladus proposals, a Titan proposal, and a Saturn atmospheric probe under consideration. We may hear word about those proposals by the end of the year “Hang tight, we’re going through the evaluations now and we’ll be announcing at the end of the year what some of the finalists will be,” Jim Green, NASA Planetary Science Director, said at the Cassini press conference Friday morning.

This list of possible Saturn missions sounds great, but they are all competing against each other and a number of other equally (and possibly more) interesting missions to other places. And with the federal budget out of control and mired in debt, there isn’t really a lot of money to go around.

Enrollment plunges at Oberlin College

11:58 am

Good news: Enrollment has plunged this year at Oberlin College due to a series of radical leftwing incidents that mark its campus as a place unfriendly to dissenting points of view.

The article also discusses enrollment drops at other radical colleges, such as the University of Missouri and Evergreen State College. Oberlin’s troubles however are new. They are not a surprise, however, when you read the article and the list of out-of-control leftist race hate that the administration there has supported.

Big news: Free speech is allowed in Berkeley

9:19 am

Last night conservative Ben Shapiro was able to give a speech before about 700 people on the UC-Berkeley campus with no disruptions or violence, mostly due to a major security effort by the city and university.

Outside, as many as 1,000 people were gathered — some protesters, others onlookers — and a group of up to 50 students occupied a breezeway at the ASUC Student Union, where they’d put up a sign, “Students Against Fascism and War,” and interacted with the crowd. They exited the building calmly just before the Zellerbach event ended at 9 p.m. “There’s a sense of relief and satisfaction that the event was able to go forward without disruption, that those who chose to protest did so in largely nonviolent ways and that, overall, things went as well as could be expected,” said UC Berkeley Assistant Vice Chancellor for Public Affairs Dan Mogulof, at a media briefing later that night.

UC Berkeley Police Chief Margo Bennett said the event was “orderly,” attended by people who were “respectful and interested” in the speaker and that it concluded peacefully.

Only a few arrests were made, and no violence occurred.

While the success of this event shows progress compared to previous events where violent thugs rioted, it is still damning to California and Berkeley and the liberal/leftist community of Berkeley that we are all surprised that no violence occurred. Instead, the need for security illustrates the intolerance of this community and its willingness to silence dissent.

In two weeks conservatives will be holding a major event on the campus, with a whole slate of speakers. It will be another opportunity for the Berkeley community to show us how tolerant they are to free speech and the open marketplace of ideas.

3D image of Jupiter

9:05 am

Another citizen scientist who goes by the moniker of mesno has uploaded a spectacular 3D anaglyph of one of Juno’s images of Jupiter.

I could post it here, but I’d have to reduce its resolution, and I don’t think this will work well. If you have red-blue anaglyph 3D glasses the image does a great job of showing the differing vertical heights of Jupiter’s many horizontal bands, especially since it exaggerates the vertical scale significantly to bring out these differences.

Mesno has done three other anaglyphs. Check them out. The image of the Great Red Spot really shows how this is a vast whirlpool boring deep into Jupiter’s atmosphere.

Orbital ATK begins assembly of first orbital repair satellite

8:49 am

Capitalism in space: Orbital ATK has begun the assembly of Mission Extension Vehicle 1, (MEV-1), designed to attach itself to commercial satellites and extend their life.

Controlled by the company’s satellite operations team, the MEV 1 uses a reliable, low-risk docking system that attaches to existing features on a customer’s satellite. The MEV-1 provides life-extending services by taking over the orbit maintenance and attitude control functions of the client’s spacecraft. The vehicle has a 15 year design life with the ability to perform numerous dockings and repositionings during its life span.

They hope to launch before the end of 2018. Meanwhile, the legal battle between Orbital ATK’s effort to build this satellite repair mission and DARPA’s effort to subsidize SSL’s own satellite repair mission continues in Congress with the introduction of two amendments favoring Orbital ATK.

Cats are liquid — if they choose to be

8:37 am

Science marches on! A new study shows that cats can be liquid, if they choose to be.

Fardin noticed that these furry pets can adapt to the shape of the container they sit in—think of a cat in a vase—similarly to what fluids such as water do. So he used the principles of rheology, the branch of physics that deals with the deformation of matter, to calculate cats’ relaxation time, or the time it takes for them to take up the space of a vase or bathroom sink.

The conclusion? Cats can be either liquid or solid, depending on the circumstances, Fardin reported in the Rheology Bulletin in 2014…. A cat in a small box will behave like a fluid, filling up all the space, but a cat in a bathtub full of water will try to minimize its contact with it and behave very much like a solid.

Anyone who has ever owned a cat will be understand this research. It isn’t that cats can be liquid that is expected, it is that cats will do what they want. If they want to be liquid, no one is going to stop them.

Because of this ground-breaking research, the scientist has won this year’s Ig Nobel Physics Prize.

Cassini’s mission ends

8:30 am

Enceladus as seen by Cassini two days before mission end

After a seven year journey and thirteen years in orbit around Saturn, Cassini’s mission ended early this morning with a dive into Saturn’s atmosphere.

The image above, cropped to show here, is actually one from a short movie, showing Enceladus setting behind the horizon of Saturn. The images were taking two days ago, but provide a fitting image for the mission’s end.

Some of the best images from the dive, including Cassini’s last image, can be found here.

While most of the press will rightly wax eloquent about the magnificence of this mission, my focus remains on what will come next. We no longer have any way to observe what is happening on Saturn. We are blind. We should not be.

ESA buys the first Ariane 6 launches

7:22 pm

The European Space Agency (ESA) has purchased the first two Ariane 6 launches to place four of its Galileo GPS satellites in orbit in the 2020-21 timeframe.

This is not a big surprise, since ESA is mandated to use Arianespace’s rockets, and the space agency is the obvious candidate for making the first commitment to this new rocket’s use.

The press release does not mention the price that Arianespace is charging for these launches, but I suspect it isn’t anywhere near as cheap as they will have to charge to truly private and commercial customers. Essentially, I am willing to bet that this contract award is a bit of crony capitalism, designed to pass some extra cash from ESA to Arianespace.

North Korea fires another missile

7:10 pm

North Korea today test fired another missile, this time sending it over Japan and into the Pacific Ocean.

South Korea’s defense ministry said it probably traveled around 2,300 miles and reached a maximum altitude of 478 miles after being launched near Pyongyang’s airport.

It was the second aggressive test-flight over the territory of the close US ally in less than a month and it followed the sixth and most powerful nuclear test by North Korea to date on September 3.

New theory for formation of main asteroid belt

11:56 am

The uncertainty of science: Using computer models, astronomers have developed a new completely different theory to explain the existence of the asteroid belt between Mars and Jupiter.

The asteroid belt (sometimes referred to as the main asteroid belt) orbits between Mars and Jupiter. It consists of asteroids and minor planets forming a disk around the sun. It also serves as a sort of dividing line between the inner rocky planets and outer gas giants. Current theory suggests that the asteroid belt was once much more heavily populated, but the gravitational pull of Jupiter flung approximately 99 percent of its former material to other parts of the solar system or beyond. Astronomers also assumed that Jupiter’s gravity prevented the material in the belt from coalescing into larger planets. In this new effort, the researchers propose a completely different explanation of the asteroid belt’s origin—suggesting that the belt started out as an empty space and was subsequently filled by material flung from the inner and outer planets.

The new theory is interesting in that it really illustrates how little we really know about the formation of our solar system. The simple fact is that either one of these theories might be the answer, even though they propose completely opposite initial conditions. We simply do not have enough information about solar system formation in general to constrain our models and determine which of these theories is right.

Until scientists have been able to study hundreds, if not thousands, of solar systems up close, these models will be nothing more than interesting exercises in computer modeling.

Hubble spots a pitch-black exoplanet

9:44 am

Astronomers using the Hubble Space Telescope have determined that an exoplanet is practically pitch black, reflecting almost no light.

NASA’s Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet’s unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.

The oddball exoplanet, called WASP-12b, is one of a class of so-called “hot Jupiters,” gigantic, gaseous planets that orbit very close to their host star and are heated to extreme temperatures. The planet’s atmosphere is so hot that most molecules are unable to survive on the blistering day side of the planet, where the temperature is 4,600 degrees Fahrenheit. Therefore, clouds probably cannot form to reflect light back into space. Instead, incoming light penetrates deep into the planet’s atmosphere where it is absorbed by hydrogen atoms and converted to heat energy.

Because the exoplanet is tidally locked, with one side always facing its sun and the other always in nightime, the nighttime face is estimated to be about 2,000 degrees cooler, and actually shows evidence of the existence of water vapor and clouds.

It is now bad to cheer for the USA in California

9:24 am

Link here. The story is about how the principal of a local high school sent an email to the families of all students telling them that they should reconsider chanting “USA!” at sports events, as such chants might offend some.

The school’s principal sent out an email to families, Wednesday and relayed the same message to students over the school’s PA system, clarifying any confusion.

She told students and parents that sometimes “We can communicate an unintended message.” She also said USA chanting is welcome, but it may be best to do it at what she says are appropriate times, like following the national anthem or the Pledge of Allegiance. School officials worry the chants could come across as intolerant and offensive to some.

You see, to these California officials, the United States is essentially an evil and racist nation whose only past achievement was to enslave minorities. To show pride in this country is to show pride in this vision, and they want to make sure their students all know this.

What a slander and lie. To me, this position not only illustrates the utter ignorance of these school officials, but their hatred of all things American. If I had a kid in this school I would now be homeschooling them.
