The gist is hate speech is not protected in some European countries. For instance it is straight up illegal to be a Nazi and say Nazi propaganda in Germany.

The fear is the "left" is going to ban hate speech and they won't be able to say racist and sexist things anymore.

I read it more and gathered that, but it still makes almost no sense as there’s the huge distinction between government restricting your speech and other people reacting to it. Plus, Musk is nowhere near a champion of “free speech” and to think he represents the principle in good faith is a severe delusion.
