Ever since they made Socrates drink the hemlock, there have been people taking it upon themselves to “protect” us from various speech in the public sphere. I think there’s more danger in handing them the power to do so than in anything some addled crank, Russian bot or Chinese sock puppet has to say. So I’m pretty much a free speech absolutist in that respect.
As Alan pointed out, however, the private sphere is different. The owner makes the rules. In my own house, if I don’t like your crackpot round Earth theories or insults to the Chicago Cubs, I’m well within my rights to eject you. I can also walk away from what I find offensive. I don’t feel it to be my or anyone else’s responsibility to force others to shut up.
