Here's the thing. No, Trump is not a fascist. No, he's not a Nazi. He's just a thick, incompetent man who's discovered populism. Fascism is at least a somewhat coherent ideology. A lot of his supporters and some of the people he surrounds himself with are nasty far 'alt' right pieces of work. Therefore, he should be opposed by all decent people, including decent conservatives.
However, even if we ignore how grotesque the policies he puts forward are and the views he (supposedly) holds, the man is so vastly incompetent, how anyone can seriously consider him suitable for even a low income job, let alone the most powerful position in the world, is mad to me. Do you think he has ever read a book? What do you think he reads? Do you think he understands the basic concepts of the American constitution? He is utterly, utterly foul. There are few people less worthy of that job than he.
'Anyone in America can be the President' used to be a positive thing people said, takes a different meaning now that infantile cretin got in. Still, at least he's funny.
