THEY HAD IT COMING.

Peter Beinart worries that

The United States is headed toward a confrontation, the likes of which it has not seen since 1968, between leftist activists, who believe in physical disruption as a means of drawing attention to injustice, and a candidate eager to forcibly put down that disruption in order to make himself look tough.

At National Review, David French agrees:

It would be painfully easy for leftist activists to position themselves close to a group of strategically-chosen Trump supporters, initiate a disruption, and then resist the instant the crowd tried to push them out. A racially-charged brawl would be endlessly replayed on the nightly news, complete with injured, bleeding victims, and national tensions would start to boil over.

Ours is an amazing country, where black people can get the shit beat out of them for hundreds of years, and chuckleheads agree that the real danger in a demagogic racist's volatile campaign is that black people might make his white supporters look bad by forcing them to beat them up some more.
