There seems to be this underlying assumption that nationalism, paleoconservatism and various commonly-held views that are wrongly called "fascism" are actually things people want to hear, and if we allow them the same access to services as any other views, their popularity will overturn this entire neoliberal scheme that's being artificially propped up by organizations like the ADL rooting out free speech in every area they can legally do so. I sort of agree - this entire project would fail without censorship.
And, if as Baron Cohen implies, we're really just a bunch of stupid hateful beasts always primed to commit another Holocaust as soon as the boot is off our neck, well...then we've got deeper problems in our society than a lack of social media censorship.
