The question of whether Muskrat's Sig Heil Salute was intentional or not is irrelevant.  It LOOKS sufficiently like this well known symbol of Nazi Solidarity that it can reasonably be construed that way.  When you couple this with Elon's equally well known political and social beliefs, it will be interpreted by bona fide Nazis to be an expression of his solidarity with them.

Would Elon characterize himself as a Nazi?  Of course not.  The problem is that in every way that counts, Elon's politics are synchronous with Nazi politics.  He believes in White racial superiority, he believes only property holders should have the right to vote, and he's part of the Fascist fusing of corporate power and goobermint.  So, looks like a duck, walks like a duck, quacks like a duck, he's a duck whether he admits to it or not.

The salute?  It was spontaneous and impromptu, so he wasn't consciously appealing to the Nazis in the audience.  Unconsciously though, Elon has seen all the same movies and newsreels we have seen, and his mind's eye know how Il Duce or Der Fuehrer looked when they capped off the end of a speech.  He's unconsciously modeling his behavior to look just like that.  To be clear, just like Hitler and Mussolini, Musk is a narcissistic megalomaniac who aspires to world domination and is convinced of his own superiority to the common man.  He believes his own race of White people is genetically superior and  should reproduce.  He's not JUST a Nazi, he's Der Fuehrer which translates to The Leader

Because of all that, his salute comes off as Nazi whether he intended it to or not.
