A Jewish doctor was fired on a suspicion that somebody who might be him posted comments on racist websites. He also had racists among his FB friends.
I’ve been following Russian and more recently Spanish neo-Nazis on social media for years. Obviously, I detest their ideology, and often the crap they write is painful to read on an almost physical level. But I do it in order to stay informed. There is great probability that the Jewish doctor is, unlike me, an actual racist. The thing is, though, it always starts with those who are actually guilty. Then it touches those who might be guilty. And finally it gets to those who are clearly not guilty but who are in somebody’s way.
