I joined Lemmy a few days ago and have been reading around. 90%+ of the content I see, even on non-politics related communities, is political in some way. I have no interest in that, so it’s tiring, especially when it’s inserted in the comments of completely unrelated posts.
The short answer is Lemmy has a theoretically near-infinite number of communities and no “engagement algorithm” so it’s up to us to curate what we want to see by blocking the communities we know we’ll never read, or, in some cases, blocking users that we can’t stand.
(Alternately you could curate just the comms you want and only browse “Home” communities)
If you want no politics there’s a number of hobbyist and nature-oriented communities, I’d start there.
I find that I want some politics, and the politics that leaks into News and elsewhere is just about right. I un-subbed from anything specifically with the word politics in it and I mostly avoid .ml, and generally I find it very pleasant around here.
