There’s a video of him doing it.

It's actually really incredible the lengths that people will go to deny this stuff. Here's Joe Rogan, one of the most popular podcasts in the world, trying to do that, yet of course does not actually show the video!

Clumsy hand movement is a signature sign of autism/aspergers and anyone who watches Musk for more than 10 minutes will notice he suffers from this a lot, but it's okay to mock people for disabilities when their politics don't align with yours. I don't agree with Musk on any things, but think it's wrong to call him a nazi over clumsy hand movement.

I have aspergers, my hand movements are terrible when I try do them to 'blend in', so I usually don't bother.

I think for a lot of people, politics is more important than having humanity for other people.
