RE: “Wouldn’t you say that Hitler was a fascist instead of a communist?”
No. Mussolini was a fascist. Hitler was a NAZI an acronym for National Socialist German Workers’ Party.
Socialism and Communism are simply two sides of the same coin, so Hitler was a communist.
So Hitler was a communist/socialist (and not a fascist) because he “self-identified” as a socialist via the National Socialist Party?
