Genuinely curious here and not trying to start a debate or sound rhetorical (I just don't keep up with the news that much) - what did Elon do that was racist?
He also annoyed me as a Brit recently retweeting some stuff that civil was inevitable in the UK because we'd let a lot of muslims in. Not that I think you shouldn't be able to criticize islam but it's very far from the reality here and there's no need to amplify a lot of bunk from people who have probably never been to the UK.
Explicitly allow and encourage racists on his social media platform?
