Nazism is white supremacy under the hood, but also, it requires brown shirts to execute their plans you know; don't you think they are almost getting there in some places and the world is regressing. They can get elected democratically like Nazis did and "then" they will subvert democracy. Trump admin is product of it and not the creator obviously. They voted for him twice so vast populations know what is under the hood. Those ideals have to be exposed to public so people at least know the details of what they are buying into, don't you think.
Germans probably know this better than anyone else. From what I understand the engine for this originally was the economically disadvantaged areas of ex-East-Germany where the apposition to socialism was ultra encouraged and they are now delivering.
