…sometimes it does feel like this.
You should check out Facebook, Twitter, IRC, NextDoor, 4chan, 9gag, or any other Internet forum (including comment sections of news articles). Reddit does not hold exclusive rights to any “right conditions for toxicity to grow”.
Yeah, there’s lots of places with rampant toxicity. I was just comparing reddit and lemmy, and I consider the Federated nature of lemmy to help prevent (not necessarily stop) toxicity from growing.
I’m not an expert on this whole Federated thing, but to me, it sounds like if one community is having problems with another, they can just disassociate and not have to deal with it anymore.
