...A Remake / Update of "The Shadow University"
@3:20 The psychology is explained in the book "The Shadow University" by Harvey Silverglate and Charles Alan Kors. It's descended from a man named Herbert Marcuse, AKA "Marcuseanism," which is itself, a descendant of Marxism. The reasoning goes like this: Because some groups("classes") lack political power, their speech isn't fighting on an even playing field. Therefore, if you're a member of an oppressed group, you have the right to interfere with the speech of those in power, to prevent further violation of your rights (to try to "level the playing field" using force). The problem with this reasoning, from a legitimate libertarian(classical liberal) perspective is two-fold
The groups opposed to speech aren't "shutting down" the communications of a violent enemy. Violence is legitimately used against an oppressor, if that violent oppression is, itself, the thing that is targeted. (The Founding Fathers' revolutionary war, or the defense of Fugitive slaves is an example of this.) However: Discourse always helps the side that's truly oppressed (Even in the revolutionary war and fugitive slaves' "underground railroad," those truly oppressed groups were on the side of discourse, and, in fact, benefited dramatically from newspapers covering their viewpoints.)
The groups opposed to speech do not recognize individual rights. In the case of the Founding Fathers and the underground railroad, violence was used SOLELY in defense of individual rights. Now, it was used collectively, but not to defend group rights, but to defend individual rights. In the case of speaking in public to a crowd of voluntary listeners, BOTH the listener and the speaker have a right to communicate freely. The leftist groups see no future where this is a RIGHT. (ie: If they get everything they want, there is no point in time at which a white male, or even a black libertarian, is allowed to speak freely.) This is because they don't actually stand for "Equal Power In Society" (the alleged, albeit impossible, goal of Marcuseanism). The most decentralized power can be is to the individual. Because some individuals will not know how to use power(everyone is born with different dispositions, interests, and intelligence levels), the best we can hope for is "equality under the law." This then means that those with diverse interests have an interest in righting legalized injustice, and each have the ability to speak and organize to do so.
In reality, the police side with shutting down free speech, because the "Offices of Student Affairs" make the University policy, and they have been protected and empowered by collectivist court precedents that deny the necessity of a criminal "corpus delicti" or "body of crime," legitimizing unlimited police power.
A similar thing happened in Nazi Germany: even though Jews and other "enemies of the state" had committed no crime, the police arrested them under "mala prohibita" laws that contained no corpus.
