I took a seat in the back of the room and listened to a rambling discourse by one of the anonymous editors of It’s Going Down, a popular antifa website, on the dangers of the alt-right and “possibilities for resistance.” If Superman had Bizarro, his physical and moral inverse, then Stickman has this guy: a beefy white anarchist of a certain age who talked passionately, if not always coherently, about the importance of physical struggle in the age of Trump.
