Unrelated to this topic, but tangential: I believe the first step in repeating history is to forget it happened. Being human is a continual process of error-driven development.
That moment may come in the future but I don’t think anyone in Europe or the USA is ignorant of what the Nazis did, and in fact the guys I mentioned (Charlottesville) seem to be pretty openly sympathetic towards nazi ideologies
They are. Those things have become a tabu. There are some "official" naratives about this and that's all.
In the end, only the nazis have something to win.
