Yup. On Reddit, people complained about users from /r/thedonald or/r/politics, so I made myself a simple rule: avoid obviously politically slanted communities and extremely popular communities. Things were much better, and I took that same rule of thumb here (avoid lemmygrad, exploding heads, and most of the larger communities on lemmy.ml) and I've been happy.

It turns out, if you actively avoid jerks, you'll probably be happier.
