There are pictures, dude. What is wrong with you?
There are pictures of Taylor Swift doing the same gesture, etc. The premise is exactly the same: a vague hand gesture doesn't mean he supports Nazism. You can't distill a vague gesture like that and try to claim it's irrefutable evidence of someone's beliefs, it's nonsense and you know it.
Elon has repeatedly stated he does not support Nazism in any way, yet that doesn't mean a thing to you because it goes against the picture you're so desperate to paint. You intentionally ignore it, which makes you dishonest.
Why don't you give equal credibility to his statements that outright deny that he supports Nazism, rather than cling to a single vague gesture that he clarified had nothing to do with it?
Oh, right. Because you only accept evidence that fits your narrative.
The real question is, what's wrong with you?
Here's some more pictures on the subject of people making 'nazi salutes' which might interest you:

Did you know all these individuals were secretly hailing the führer? There are pictures, dude, you can see them, proof right there, indisputably nazis the lot of them.
Or... maybe... these are not nazi salutes. Probably. Certainly. Pictures notwithstanding. Just like those other pictures (, dude) you referred to don't show nazi salutes.
What will it be? All your idols turn out to be nazis or none of them nor Musk even though you don't like the latter?
