Gregory's ServerIt is quite easy to see that "pure" out in the open fascism raised it's ugly head in the mainstream almost at the same time the last generation that first hand remembered WWII died.
Because that generation KNEW Fascism was more than "funny looking men that yells a lot", but now a lot of people think that it is, and therefore don't think that what they see, or even participate in "is fascism", because the "black and white funny mustache man" is fascism, "not what I am doing".
@WhyNotZoidberg another factor is years of corrupt governance by pro-business candidates and war hawks, and the decline of the social-democratic post war consensus.
