Antifa scholar Mark Bray is in the hot seat for asserting that "self-defense is a legitimate response to white supremacist and neo-Nazi violence." He's right. When antifa activists act to shield non-violent protesters, as they did at Charlottesville, they are acting nobly. But when they wantonly assault peaceful demonstrators, as they did at Berkeley's Civic Centre Park on Sunday, or when they riot to intimidate university administrators, as they did at Berkeley in May, they are no more virtuous than the mob they despise. All the apologia the counterculture can concoct—including Todd Gitlin's recent musings about the "fearful asymmetry" of left and right—cannot change this simple rubric.
