Yeah. I guess it will vary from instance to instance, but from my personal experience, viewing "All" on Lmemy isn't noticeably more political than /r/all. There's maybe less diversity in the stories, and more memes, but still. It's not bad.

Reddit has absolutely been way worse at times, by the way. When T_D was allowed to run roughshod over the front page, and spez bent over backwards to not ban them despite clearly being a nuisance and breaking the rules.
