There is no "alt-left."

The people whose protest got out of hand are regular people, normal students who cannot stand by and allow racism and hatred to be spread on their campus.

Let these racist/white supremacists hire a room to speak off-campus, where they belong, and see how much of an audience they get.

And there is no guarantee that the rioting and burning was done by students. It's quite possible it was done by agents provocateurs from the alt-right. Just saying.
