The guy is screaming for attention. So, why do you (and why should he) expect to me immune from criticism. He doesn't treat other people well, so why should he cry if some people criticism him?
It's not like we are promoting hate groups or firing him.
Personally, I pretty much ignore him because the big issue to me is the climate. We need to fix that.
Life is too short to waste on Elon Musks Tweets about the World Cup or anything else.
