Huh?
The Nazis were not Fascists. They were National Socialists. The Japanese were not Fascists. They were emperor-worshipers and Shintoists. One might argue some similarities with Mussolini-style Fascism in government support of major industries in Japan, but Mussolini would never have recognized it as Fascism.
If we're going to turn the word Fascism into nothing but a label for things we don't like, then we lose the ability to describe a specific set of beliefs. As the philosopher Wittgenstein wrote, "The limits of my language mean the limits of my world.." Turn the word "fascism" into a meaningless noise, and we can no longer identify it when we encounter it.
Historically, the National Socialists in Germany were lumped together with the Italian Fascists so as not to upset our ally, the Union of Soviet Socialist Republics.
