The Chronicle of Higher Education does a more honest job of describing these events. The movie is slanted and wonderful for people who want to live in a delusional world of alternative facts.
Colleges cannot afford to spend a million bucks to protect rabble rousers who self-invite themselves to appear on campus. Some now face a hurdle. They have to go in search of a student group willing to sponsor them. The University of VA was stuck with one of these undesirables who organized a march that resulted in the killing of an innocent bystander. Other schools have spent hundreds of thousands on security only to have these white supremacist conspiracy theorists chicken out and not appear. Basically, educated people have no need to listen to backwards, racist Richard Spencer.
