I think this is awful for free speech because you're removing people's autonomy, creating an echo chamber sound bubble for far left views, and isolating people on the right which...ironically creates a echo chamber for them as well. Hell, it even confirms for someone like Spez on reddit or Elon Musk on Twitter that "they are the barons of true free speech because we won't ban you when you say something we disagree with". Completely awful behavior.
It takes a strong stomach, good articulation, and about the time to take one shit to present a well reasoned argument for someone with views you disagree with. God forbid someone should be slightly uncomfortable.
