Currently on TV is a WW2 documentary narrated by Tom Hanks. It's pretty good, with significant coverage of nazis. I recommend watching it. I'm a bit of a history wonk, and have read extensively about WW2. I'm afraid I don't see any parallels between the nazis and Musk.
The rhetorical parallels between Musk, his affiliates, and the nazis should be clear to anyone with remedial knowledge of history, let alone someone who calls themselves a wonk: scapegoating racial outgroups isn't a subtle strategy and Musk's pursuit of the strategy is not subtle.
WW2 is the end of nazi politics, not the beginning. In the unlikely case that you missed the parallels in good faith, I recommend the Richard Evans books to learn about the beginning and middle of the nazi movement.

Here's what Musk actually does when he intends that gesture: https://www.reddit.com/r/centrist/comments/1i8ajx0/video_of_...
And here's what this one looked like: https://www.reddit.com/r/gifs/comments/1i6par1/elon_musk_vs_...
Go on - would you give the latter link's "my heart goes out to you" gesture publicly at, say, work, or outside a synagogue?
I have to imagine it's motivated reasoning, because of the people who say it was a Nazi salute, approximately 100% of them already hated the guy. I've seen no one suddenly swayed. Fwiw I have no strong feelings about Musk either way, but to my eyes he is obviously not a Nazi.
Because we who read history all know that the "Nazi salute" or even the very American "Bellamy salute", and the Roman salutes before them, were directed to the leader, or a flag. And the Nazis in conjunction with saying "hail" to their leader. So far, so good?
But Musk was standing at a podium and looking out upon a crowd of people...voters...delegates... and he did not, in my view, try and face President Trump, or any leader standing at another podium, when he directed his salute outwards from the podium: outwards toward the crowd, opposite the camera angle.
So if Musk was not saluting President Trump: was he saluting a flag? Or the citizens? Because if he was saluting the citizens in this way, it gives a very, very different interpretation to the entire gesture, and if he was not saluting the president, or some leader, I do not see how this could be interpreted in the same way as the traditional salute of any type.
I asked whether he had seen any of them making the Bellamy Salute, but he said no. I suppose he was too young to see it. Hail Caesar.
