Can't reply to the parent comment directly, but no, they're not arguing in good faith. The Wikipedia article has a gif of it:

That wasn't a wave and the other commenter is full of shit.

Yes, the whole motion matters. I've seen lots of historical documentaries with footage, and I've never seen a nazi salute with that motion.

You have to really work at it, to think Elon made such a salute, but others have not. It's ridiculous and absurd.

When I see and hear mad lunacy amd character assassination such as this, I immediately think "well everything else said about Elon must be made up too"

You speak of "good faith", do you know what this means?

It means that best intentions should be presumed, not worst, when examining the acts of others.

Have you done this?

There is also the REALLY strange expression he has on his face when he does it. No one has that expression when just "waving"

My heart goes out to you.
