It's so much easier to comment on Lemmy because it isn't a toxic cesspool waiting to tear you apart
It feels like people are a lot nicer here than on Twitter and Reddit, and even when people disagree, it's generally civil and not an all-out flame war. Also, there's no algorithm promoting outrage all the time.
For me, the anticipation of toxicity was a huge deterrent for me ever participating in real discussions, but here I feel like I can be myself.
I'm surprised of how many replies I have had to my own replies with people actually adding to the conversation and being polite. On reddit I barely got any response and most of it was tangential to the subject at best.
