Who cares about the pictures? There is a whole video where you can see that he does historically accurate nazi salute then turn back and do it again. Stop talking about pictures, always show video of what happened.
Find me a video of someone else doing the same and tell me it's the same. You won't, because what you see in video is much more obvious that what you see on pictures.
People are dump to only show still photo of Musk with this salute. Everyone know you can take picture out of context, when you watch full video it's much harder to do so.
Must was clearly showing it intentionally. Maybe because he's a troll (I wouldn't be surprised), maybe because of other reasons (I hope not...).
