90% of the time I see a comment like this, the “differing opinion” was something along the lines of “trans people have a mental disorder and we shouldn’t encourage them to exist by allowing them to transition” or “it should be legal to discriminate against black people”. No one gets banned for their conservative fiscal opinions lol
A strategy that has worked for me: very quickly browsing all new, just looking at community names. I barely look at the posts, just make a quick decision if it sounds interesting to me. I’ll check the sidebar and decide from there to subscribe or not. I’ve found dozens to follow and a bunch to block lol. It’s cleaning up my feed pretty nicely and my home page has a lot of content now.
