Hitler wrote of his admiration for Mussolini, but when it came to naming his party something they did not call it fascist (according to Konrad Heiden, Hitler did not want the party to be called National Socialist but that's another story).
Did the Nazis' opponents use the word fascists to refer to them? If so, did any of them object to being called this in speeches, articles, etc? Or viz their modus operandi, did the Nazis go out of their way to beat people up who called them fascist?
Edit: per my comment about the Nazis beating people up, I'm asking whether their opponents in Germany called them fascists. The Allies justifiably called them every name under the sun once the war had started.
