Fair enough, I see that online all the time. Here’s my take.

Raising your hand alone is a common gesture that pretty much everyone has done. Saying “my heart goes out to you” gives plausible deniability. But making the hand gesture while clicking your heels together and snapping to attention with a stern jaw-jutting look on your face is pretty unmistakably a nazi salute.

Elon has publicly denied it was a nazi salute, but any normal person would go a step further and also disavow neo nazi ideology in the same breath. But doing that would break the dog whistle effect.

Some people say he’s just trolling, and yes, Elon likes to troll. But trolling or not, it has the same effect if you don’t also renounce neo nazism. It normalizes and shows you are comfortable with it.

Can I prove he’s a neo nazi? No I haven’t gone through his wallet and found his membership card. But his support for the AfD and all his great-replacement-theory adjacent talk are strong signals.
