The Rioter's Veto

Mayor Arreguin (SFGate)

Berkeley Mayor Jesse Arreguin believes in free speech, except for right-wingers:

“I’m very concerned about Milo Yiannopoulos and Ann Coulter and some of these other right-wing speakers coming to the Berkeley campus, because it’s just a target for black bloc to come out and commit mayhem on the Berkeley campus and have that potentially spill out on the street,” Arreguin said, referring to militants who have also been called anti-fascists or antifa.

Mayor Arreguin is saying that the "rioter's veto" is a legitimate reason to forbid speech.

Opponents of Black Lives Matter, I'm sure, are paying attention.
