You are responsible for your feed. That means you need to actively block what you don’t want to see. You can block on 3 levels. Block the Author, Community, or Instance. It’s very effective. Start wide, then go narrow. After a few weeks of scrolling and blocking, now I don’t see any politics and I engage with posts I care about. Sure, there’ll be random comments still I encounter trying to bring that stuff into the discussion, but more and more time now passes between having to block individual people.

One thing I agree it is harder to do for are general communities like this one since there are no word filters. But again that’s a risk you take allowing general communities in your feed.
