The only thing that happened was a bunch of pathetic, annoying, dick for brains college students decided they couldn't have a grown up debate over an issue without being violent and destroying property. The same thing happened at Columbia University when the leader of the minute men came to speak.
The lefts assault on free speech knows no bounds. I thought liberals were supposed to be more intelligent than conservatives and better suited at using their words, rather than their fists to solve problems. Can anyone name the last time conservatives rioted on a college campus when a liberal came to speak? Liberals are anti war, but become violent when someone disagrees with them. Liberals preach tolerance, but are intolerant of anyone except liberals or "oppressed minority groups" that hate liberals- ie Muslims.
Mental disorder, or just sickening and transparent hypocrisy? Take your pick.
