Okay I thought this was just typical media stuff but I just watched the video and it does appear as though Elon made an awkward gesture in a moment of enthusiasm

The gesture is not what they're calling it 
It's different

This symbol is an ancient Hindu symbol not the more recent German use, totally different meanings

Can you give some keyword about it? So I can look it up see what it is.

Unfortunately I am unable to process this request due to my personal distaste for the symbol and the historical movement associated with it

Totally undertand, I’m gonna dig into it a little bit
