What happened in Charlottesville was bleak. I'd wager that Antifa probably started the majority of the violence, but in any case, it's clear that many in the Alt-Right came looking for a fight, and the two groups seemed more than happy to beat on each other.
Right now people seem to be arguing over who's more to blame, or who's worse, but frankly I think that's ridiculous. Both sides are regressive, both sides are un-American, and both sides engage in the exact same identity politics. There's plenty of condemnation to go around, and there's no need to pick and choose here.
