From the second article: “Since 2002, Montgomery County Public Schools has engaged in social justice and diversity training for staff members and students. ”

Social justice is just a way to punish a person over here for the deeds of someone else over there (in space or time), just because they have some resemblance, relation, or connection to that someone else. The best part of social justice (for those “Justices” who mete out that sort of justice) is that their victims receive no trials and no defense. The self selected “Justices” accuse, convict, and punish their victims, and the rest of society allows them. The social justice training is how to unjustly perform these activities on their victims in a way that minimizes trouble from the rest of society.

The main purpose of social justice is to shut up and shut down opposition to socialist and tyrannical activity, and another good part — for the “Justices” — is that they get to practice tyranny while meting out their form of justice. The “Justices” have become good at that:

It is kind of like The Tiny Dot, except with unjust punishment instead of punishing taxes:
