What I really find annoying is that Reddit never comes up in these discussions. Just because people tend to agree with the bias doesn't change the fact that it has no doubt left people radicalised. I was watching an Ezra Klein interview with some pollsters after the election, and it even shocked me the level of difference between what polling showed as of importance to most Americans, and what Reddit portrayed as being the common American opinion.
It's a cancer, just like Twitter, but no one ever mentions it. Not even Trump, who you would think would want to squash this safe space.
(I am indulging a bit in conspiracies, but the Elgins Air Force Base conspiracy seems more and more likely given how this site goes unnamed in the US, despite being so busy and so weird)
