So in your world it is acceptable for me to say that you're an evil person for disagreeing with me and should be shot where you stand?
That's absolutely ridiculous, and actually a crime in a decent number of the countries. And if that's not what you're saying I think that you don't actually know what your free speech maximalism means, because people who believe those things and say those things exist and they want to hurt people.
Then explain why i cant scream FIRE in a movie theater, or call a mall and tell them I'm going to bomb them, or walk up to someone on the street and say "give me all your money or i'll blow your brains out". After all its all just speech isn't it?
