@IllNacsAnd even if we remove the obvious pitfall in your argument that two people have pointed out already (that you're on a private forum at the moment with it's own rules), free speech isn't, and never was.
The definition you use is for "freedom", not "freedom of speech".
(as in, action and consequence), and no country/society is "free", we've always had rules to get along in societies for a reason, across the planet as far back as recorded history.
I'm going to assume you're from the US based on that take on free speech, so i'll focus on that for now.
Ironically, some of the limits of free speech in the US is false statement of fact/slander/libel, and you know what, i think i'll just leave that there.
(oh yea, and obscenity)
