As someone once said, freedom of speech does not extend to yelling FIRE (for fun) in a crowded theatre. People can get hurt.
There is no need to use ultra-violent language to express opinions or critique. If e.g. Steve Bannon dislikes Dr Fauci, he can say that he dislikes or distrusts him or whatever. He doesn't have to say he should be beheaded, for chrissakes. There is no possible justification or "use case" for that turn of phrase.
Some of what we call hate speech is merely insulting, immature, bigoted, etc. But implicit or explicit death threats, rape threats, kidnap threats, stalking threats -- all those things are over the top and it is hardly "censorship" to subtract them from the public discourse.
