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.
