I’ve noticed an ebb and flow to that. It seems like anger goes down when activity goes up, which is the opposite of what I would usually expect from the internet but that’s how it’s been on here. I have an account where I filter/block things and one where I don’t so I can see what’s really going on, and when there’s too much hate and rage content on the front page I take a break from lemmy for a while.
I think most of the people who say lemmy isn’t toxic at all are probably people who found a bubble where people don’t push back on their personal brand of toxicity very much.
