I don’t see that. Racism (oh the racism), misogyny, homophobia (etc.) are everywhere on Reddit. It’s full of shit. The content sucks.

My pet theory is that a lack of moderation is responsible for that. Ask Science has excellent moderators and is doing well. Many other subreddits (especially the big ones) pick a very laissez faire approach and consequently manage to sound more like Stormfront in the end.

All the horrible people who are thrown out everywhere else can just continue hanging out at Reddit.
