Your parent comment sounded like you said that Nazis are not fascist. Fascism is a broad historical tradition, and of course contains Italy, Nazis, and a whole host of other terrible stuff. I should know: fascists are my enemies, as they're directly ideologically opposed, and there's a long history there, as well as personal, real-world political work.

Anyway, I think the fine line of disagreement here is that I personally see "Nazi apologist" as someone who is an apologist for _all_ of National Socialism, not just certain policies. You may be correct that today, people could consider anyone who's denying the holocaust to be a "Nazi apologist."

Does that make sense?
