To the people downvoting this comment -- it isn't just that Musk made a couple of very sharp nazi salutes. You may say, oh, that was just an unfortunate similarity, he wasn't doing a nazi salute at all. But he has a history of boosting nazi posts on twitter. Oh, Musk posts so often he can't vet the source of all of his retweets. But if those are mistakes, the fact is he never makes a mistake in the other direction, which strongly suggests it wasn't an accident.
