Unpopular Opinion

Nah reddit has WAY more censorship it's just you don't see it because their mod logs are private. Not sure if Undelete is still around but you can see what a thread looks like with deleted comments in-line and sometimes it's like 90% of the thread is just red comments. That's not even counting self-censorship people do when they're on their second chance or just not wanting to tank their score with downvotes.

That being said you have sh.itholes like NonCredibleDefence and most of Lemmy World where they'll just outright permban you if you contradict their narrative. While a minority, that's going to be a big part of your impression of the federation if you get caught up in that.
