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.
Block em. I blocked nearly every community about USAian politics and my feed is now quite OK. Also block people who make everything political. There will still be enough out there to interact with, trust me. I’ve blocked swathes of people here and still find it entertaining. Also, do your best to contribute non-political content, it’ll help provide others something to comment on that isn’t political (and of course block those that try to turn it political).
Also, do create multiple accounts per activity. A political account, a non-political account, a gaming account, a botany account, a bird-watching account,… whatever your interests are, make an account for it and curate your content. I have multiple and this is probably my most political one. Others barely mention politics and aren’t connected to this one. Until lemmy or other fediverse software allows creating personas on the same account, this is the solution I find works best.
In other words, there is no real algorithm here that will secretly bubble up certain type of content depending on how you interacted with the platform. You more influence on your own experience than you know.
