What point are you trying to make, Mytton?
That Elon Musk is normal?
I don't like the idea of appropriation, it's like the American Black women/men getting angry with white people who wear Dutch braids but they're called "Dutch" braids for a reason! The Nazi's didn't invent that type of salute, it's been part of human culture for centuries, it's unfortunate that it has been associated with Nazi's but how long will it be before we can't make any hand gesture because of some evil connotation?
Elon Musk has done a lot of good for humanity, like his internet satellite system, his rockets saving those stranded astronauts, saving the planet with Electric cars, that brain link which helps the handicapped and a lot of other stuff.
