People frown upon lemmy.world because it’s a politically American center-right instance on a leftist social media platform that bans leftist discourse via defederation.
If your politics align w them and you don’t mind them deciding what you can and can’t see on your behalf, you’ll do fine there.
I switched from lemmy.world because of that and switched to an instance that doesn’t make a habit of defederating from the most active instances (ie hexbear) and there’s also another center-right instance named lemm.ee that also doesn’t defederate.
Np and I can see that you’ve gotten an introduction to the political culture war that’s being waged on lemmy (assuming you weren’t already aware). Lol
One more piece of info that I wished someone had given me when I first started is that a huge majority of lemmings are cool; but there are significantly more center-right users than leftist users so you’ll see more of the vitriol you witnessed in this post coming from the center-right instances like lemmy.world and lem.ee, but the leftists are a scrappy bunch so they’ll respond in kind and mostly from hexbear; hence the defederations.
