Believe it or not, me (not white, did not grow up in the West, had the faintest clue about Nazism) used to do what you would consider a "Nazi salute" when I'd see friends and wave to them from a distance. I don't know how I picked that up but it happened.

I'm not saying that Musk is doing the same; but that one can be charitable and say he probably did not mean that. I mean, what does he stand to gain from doing so? He's a businessman.
