dax, have you not seen the video of Elon doing it? Because I agree, you can screen shot anyone who has been in front of a camera for hours of their life and they will probably have had their hand out at a 35 degree angle at some point. But do you have any videos of non-Nazis pounding their chest, and then holding their hand out at that angle? Twice in a row?
The most generous explanation is that he did it as a troll.
But if he is a genius, and has a grandfather that moved to South Africa because he was so pro-Apartheid, and also said "The natives are very primitive and must not be taken seriously... Some are quite clever in a routine job, but the best of them cannot assume responsibility and will abuse authority. The present government of South Africa knows how to handle the native question", and had a father who followed in those footsteps.......He knows exactly what the Nazi salute is. And what he did on stage is identical in pace and action to it.
So let's just Occam's Razor this bad boy; Is it more likely that he did or did not know what the Nazi salute was?
