I've pointed to two examples that we've already seen - that Milo guy who instructed people at his talk to target a specific student (who did not attend the event) for harassment for being Trans, and Richard Spencer who is simply a Nazi wannabe. Both have had attendies shoot at people.
That Milo idiot was once chased off of UC-Berkley by anarchists who overwhelmed police, as he was supposedly planning to out specific students again. The only other incident Cheeto Benito is referring to is an incident where one non-student punched another non-student for passing out obnoxious flyers on campus - campus police aided in IDing and arresting the first man, and he is currently charged with 3 felonies.
I look forward to the Louis Farrakhan/NOI campus speaking tour, though. We can all sit and listen to him lecture on the savagery of "the white man", and why the Jews are "vermin". Unlike the above idiots, at least he provides a pretty disciplined security team, and doesn't have followers running around shooting people.
