Setting aside whether or not Elon was trying to do a Nazi salute (as people have made up their minds on that and aren't going to change), it is factually false to call him a "literal Nazi". The Nazi party doesn't exist, there can't be literal Nazis any more. At most you could accuse him of holding to Nazi ideals, but please be accurate in the accusations you levy. Exaggerating by calling someone a "literal Nazi" is extremely unhealthy for society.
