Absolute free speech is more of a thought experiment than something that's possible, so I don't really see it as sad that people are only referring to American-style free speech (No libel, fraud, fighting words, calls to imminent lawlessness) when they say "free speech", I see it as practical.

Absolute free speech would imply even a lack of self-censorship. I think if you deeply analyse communication you sort of realise that it's fundamentally built on censorship. Censorship is a core communication filter function. Getting rid of censorship absolutely is actually absurd.
