IMO, the issue is that Musk’s gesture, and that of Laura Ingraham a few years ago, are the kind of thing that anyone who abhors what Hitler and Nazis stood for would avoid like an elevator full of lepers. This isn’t an oops like pointing with a single finger which may offend some cultures with which you are unfamiliar. This is a gesture synonymous with the most hateful movement in the West post enlightenment. If you have grown up in Europe or North America you cannot be unaware of what that salute is. If you can complete the gesture well enough for it to be confused as such, you’re obviously not too concerned with casually being mistaken for the sort that would commit genocide. How is that supposed to be a mitigating factor? I’m not a nazi, I just can’t be bothered to avoid looking like one.
