Thugish, violent lunatics. A a rabid mob, literally foaming at the mouth when confronted with any opinion that doesn't line up with their narrow-minded worldview. Video is courtesy of the Anteaters For Israel club. AFI has been the primary student group trying to expose UCI's vicious culture of anti-Semitism - a culture that the UCI administration has spent the last half-decade either shamelessly excusing or trying to cover up:

Men on one side and women on the other. Truly, this is a progressive organization that the left should feel very comfortable supporting.

And here's Pipes discussing the incident and the tape. The protesters called for genocide and for the violent destruction of Israel, and in response the University basically congratulated themselves and the students. AFI member Reut Cohen has the full text of the University's self-congratulatory moral cowardice, and she links to a more brutal critique of it by Pipes.

This is what happens when you allow Saudi money money from local mosques to turn your campus into a platform for the worst kind of anti-Semitic Islamic radicals. Well, that and you become a breeding ground for actual, real life terrorists. Maybe the administration just thought the genocidal hate speech was "education" - that's their usual excuse.
