> for example, in a "free" twitter, i could post some racist tirade, and expect it to gain no traction/retweets from my followers & some random others. people might see it, but it is principally no different to making the same speech in the city center: i'm going to be heard, but no one is going to listen.
This is the biggest misconception many proponents of absolute free speech have. Many movements, both good and bad, have begun in social media (Twitter / Facebook, etc.). Everything from the Arab Spring, to BLM, to Unite the Right in Charlottesville and January 6th, were at least in part organized on social media. Just because _you_ don't think an idea is worth listening to, does NOT mean that there aren't hundreds or thousands of people who disagree and will listen. I don't know what the solution to this problem is, but to assume it's not real is just plain wrong.
