Exactly. Students and faculty displayed "overwhelming opposition" when the speaker was invited. So what? That's no reason to cancel the event. If anything, it's a reason to promote it. That overwhelming opposition doesn't excuse their behavior, either.
Setting things on fire in response to having to hear someone you disagree with. Actually, scratch the "have to." You could no go and keep living your life. Ridiculous.
BTW, this is the kind of **** that goes on at universities and yet many folks want taxpayers to subsidize so it's "free" for everyone. No thanks.
