Finally, there was Antifa’s recent attack on Andy Ngo, a freelance journalist often associated with the pro-free thought cultural publication Quillette. At a demonstration in Portland, at which Trump was a focus of dispute, Antifa fighters beat up and milkshaked Ngo, apparently because he was there and he was not on their side.

The president is not always at the center of such demonstrations, but Antifa has become an angry and violent fringe force in the Resistance. It has played an ugly role in a number of events, most notably Charlottesville, in which feelings about Trump have played a role.

Shunning, shaming, doxxing, attacking. As the 2020 campaign reaches full speed, would it surprise anyone to see all of it increase? And all from people who congratulate themselves for standing against hate. Perhaps our politics will cool down at some point in the future. But not now.
