Because they are foolish

Maybe Musk could be legally responsible in some jurisdiction for things he has said, or for things hosted on a platform he owns. But we should almost never encourage the idea of arresting people for things they say. Yes, there are limits: threats of violence and fraud are both types of generally illegal speech. Yet charging Musk for being a loud public idiot is a very bad idea.

Musk cannot be charged because he is a stupid. It’s a responsibility that he doesn’t have.

The foolish cannot be detained because they are foolish. I fully share what Nick Heer writes, despite Musk itself.

[…] a troll X account posted a screenshot of a 4chan post about “low T men”, itself containing an arguably antisemitic meme, which was quoted by Musk calling it an “interesting observation”. Just more evidence Musk is a big, dumb, rich, influential moron.

Certainly there will be more concrete motivations.
