"Free speech" absolutists don't convince me with their hypotheticals.
Believe it or not: absolute free speech is not the end goal and not as valuable as you all believe.
Forbidding some kind of speech can be okay.
Because not forbidding it creates an awful lot of very real and very current pain. Somehow the theoretical pain that a similar law could create is more important for your argument, than the real and avoidable pain thatthis law is attempting to prevent.
but e.g. American free speech would be nonexistent
And I say that the specific American flavor of free speech is not very valuable at all.
