There are twin goals: total freedom of speech and holding society together (limit polarization). I would say you need non-anonymous speech, reputation systems, trace-able moderation (who did you upvote), etc. You can say whatever you want but be ready to stand by it.
One could say the problem with freedom of speech was that there weren't enough "consequences" for antisocial behavior. The malicious actors stirred the pot with lies, the gullible and angry encouraged the hyperbole, and the whole US became polarized and divided.
And yes, this system chills speech as one would be reluctant to voice extreme opinions. But you would still have the freedom to say it but the additional controls exert a pull back to the average.
