When you use words like Musk can "behave". What you are suggesting is there are some sort of norms which you think he should be conforming to. The whole word "behave" is not one commonly used between adults.
Who gets to decide how Musk acts? You? People you agree with?
In theory anyhow, we live in a country where free speech exists. Clearly that is not the case in China.
This is I suppose where the phrase "Cancel Culture" starts to show up. I've always hated that phrase, but when people start talking about dictating how people should 'behave', it certainly starts to feel that it's appropriate. We should punish Musk for what he says. He should not be allowed to suggest he agrees with a political party we don't like!
Sounds like talking to children.
