"Uh, he's right – I better not talk to you," said the young Trump voter I'd been speaking with. I guess in Trump's America, anyone's just a Google search away from some kind of blacklist. For the record, I don't think Trump voters are Nazis – well, except for the tiny handful who say that they are – but one can't sit through the ritualistic pageantry of a Trump rally and wonder where he plans to take this thing. The venue may be a red, white and blue hockey rink in the American heartland, but the rallies, the braggadocio, the unfettered grievance against journalists, professors and other despised elites all carry ugly echoes of the worst that the 20th Century had to offer.
