Trump is accurately described as a fascist, yes. He's more Mussolini than Hitler though.
Wouldn't post-fascist be yet more accurate than fascist? Unlike 20th century Fascist revolutionaries and like National Front and similar European parties, he doesn't advocate establishing dictatorial rule in place of present institutions, but rather, pushing democracy to its limits within a country's present constitutional framework.
Also, I probably should have been more careful with my phraseology, but yes, your rebuttals are valid. He still does not strike me as Hitleresque, though.
