There are plenty of racists who aren't fascist. There are plenty or countries with racism problems that aren't fascist. There are plenty of dumbfucks who aren't fascist. There are plenty of illiterate countries that aren't fascist. "Stupidity" (im being careful here - i dont think illiteracy = stupid) and racism predates fascism.
Youve reached the limit of the liberal ideological framework and have resorted to explaining fascism as some sort of cultural pathology. This is what happens when your idealist politics prioritizes individual psychology and moralistic explanations over historical and economic analysis.
It's frustrating seeing liberals watch the fascist devolution in real-time, and just throw up their hands saying "well i guess americans are just stupid! QED!". It conveniently absolves them for their complicity in facilitating fascism, and it spits in the face of victims of US policy, both foreign and abroad.
Yup.
What we are seeing now is a critical inflection point for liberals: do they do honest introspection and start to apply real criticism to the history of the US, or do they cover their ears and claim Trumpism is an aberration for which they have no reasonable explanation.
To put it simply, liberals now have a choice between
"Damn, this is really the outcome of the american political project, huh? How did we get here?"
And
"Trumpist fascism is un-American, and I am clueless as to how it took hold, but I am going to continue to vote blue no matter who!"
If the amount of liberals on .world bizarrely harkening back to the "good old days" of the founders, Reagan, Obama, and even dubya is any indication, I suspect most of them have gone with the second option.
