Extreme leftist politics, memes, linux, a weirdly active Star Trek community (comparatively) and blocking furry/anime porn communities daily. That's been my experience so far.

I feel the same way sometimes. I'm a centrist as well, a lot of the people on both sidee in this platform do have extreme takes and have the "You must agree with me or I will ban you" attitude. I wish it was a bit more diverse, whenever I come on Lemmy it is completely saturated with leftists post. I have nothing against people on the left, its just the fact that content is so obviously saturated with it.

I left Lemmy for like 6 months because I got tired of the echo chamber. I'm usually inclined to the left but this was just too much and too extreme. There were some pretty interesting topics that I learned here, like how badly designed society is and why cars are an artificial need. Those "intellectual" discussions (if you could call them that) kept me engaged, but even those spaces were ruined by people totally closed to the idea of a middle-ground.

I'm not actually seeing tankies around, any more -- lemmygrad banned me within days so that their minds wouldn't be polluted by my arguments, and whatever happened to hexbear I don't know they seem to have largely defederated again.

I am honestly put off by people who really go by Marxist-Leninist schtick. This whole thing reminds of the old anecdote about a dialogue between a jew and God about the Holocaust: "I guess you had to be there". Seeing privileged white kids run around the internet calling for good old Lenin/Stalin times are no better than bonehead Nazis fighting their own fears materialized as Yet Another [racist slur of your choice].

It's entertaining for like five minutes, but the joke gets tiresome very quickly.
