> Would it be better if they called Elon a fascist? He did the fascist salute, after all.

No, you mean to say “nazi salute” because it was used by NSDAP during WWII. The point here is that “nazi” now means “baddie”, and “fascist” is even worse because most people who are called that have nothing to do with Mussolini, either.

> if it endorses authoritarian far-right parties like a duck, has controversial white-supremacist parents like a duck, and does the fascist salute like a duck, at which point do we start wondering wether he’s actually a duck?

Cute. You can wonder, of course. That seems extremely warranted. But you can’t conclude based on the current evidence.
