i'm not a free speech absolutist, and i've never claimed that i am. rather, i've often contrasted myself against a chomsky-type character that advocates for essentially no restrictions on speech at all by suggesting that i support restrictions in scenarios where a group has the possibility to inflict legitimate harm. the very careful, difficult and subtle point is trying to figure that out: does whatever group of thugs and demagogues actually pose anybody any threat, or are they just a bunch of dumb bikers, or something? it's very tricky, and there's no clear rules, you have to kind of figure that out as it goes.
so, if i saw a serious neo-nazi march that was actually out to hurt people, i would strongly advocate shutting it down. if i saw a couple of kids with backwards swastikas on their hats that they picked up in a buddhist shop and thought were nazi symbolism march down the street singing du hast, i'd be a little less willing to get assertive.
but, that's not the key point i want to make.
the key point i want to make is this:
free speech is not the idea that you can say what you want without consequence. free speech is the idea that you should not be restricted from saying things that you may face consequences for saying.
the former position is held by people like ann coulter, who argue in favour of free speech in self-serving ways, and do not actually understand it. the second position is that pushed by centuries of western liberal philosophy, who attempted to try to find a middle point between freedom and what they may have defined as some kind of pre-civilizational hobbesian fantasy reality.
i've been over this enough that i don't want to bother with it, but i'll point out the following, point form:
1) free speech is about a social contract between individuals and governments. it's not about private property, not about employment and not about conversations between private individuals.
2) free speech is not about "open discourse".
3) people that are offended or affected by the speech of others also have speech rights, and the right to disagree with the people that offended or affected them.
