You can’t actually be serious can you?
Reddit back in the early 2010s was infamous for worshipping Ron Paul. In the early and mid-2010s there were literally subreddits dedicated to racism. It was controversial in the 2010s to ban or censor anything, meanwhile today all of the big subreddits are run by a handful of mods who will ban anyone who says something they don’t like, or even ban people automatically if they comment in a sub they don’t like.
If you think Reddit is somehow more right-leaning today than in the 2010s, I think that might just mean that you became far more left-leaning since then and everything else looks right-leaning in comparison.
/r/antiwork, /r/murderedbyAOC, /r/leopardsatemyface, /r/politicalhumor, /r/blackpeopletwitter, etc. I could go on.
What’s the biggest “right wing echo chamber” on Reddit? /r/conservative has just barely over 1M subscribers, which puts it at a fraction of the size of those subs mentioned above.
