Interviewer: Right. So you can't incite people to violence like a direct incitement to violence. You can't do the equivalent of crying fire in a movie theater, for example.
Elon Musk: No, that would be a crime.
Shouting fire in a crowded movie theatre is not, and never was, illegal. It was an analogy in a court case which was then overturned. https://en.wikipedia.org/wiki/Shouting_fire_in_a_crowded_the...
Interviewer: But here's the challenge, is that it's such a nuanced difference between different things. So there's incitement to violence. That's a no, it's illegal. There's hate speech, which some forms of hate speech are fine. I hate spinach.
"I hate spinach" is not hate speech, and importantly, hate speech isn't even illegal.
