I wish we could have a higher level of discussion, with an expectation that claims should be supported by evidence. Less ad hominem and conspiracy theories about everyone with a different point of view being a bot. And much less "I heard someone from [group I dislike] say [comically evil thing]," being accepted purely off hearsay with no source.

I think lemmy unfortunately inherited some toxic reddit traits in that regard. If you make something up, whole cloth, that tracks with what people want to believe, you get upvoted, if you make a case with strong supporting evidence but it doesn't fit with what people want to believe, you get downvoted - it's circle-jerk-y.

Also, people just seem generally incurious about the world and it's rich, diverse history, and just want to rehash the same talking points over and over again. Too many big communities are focused on news or current events, not enough on broader historical context or philosophical discussion. I don't really want to rehash the same discussions about the US election over and over again for the thousandth time. When history is discussed, it's at a meme level, with a handful of historical events being referenced exclusively, oversimplified and weaponized to own your political opponents. The world is filled with color, depth, life, and wonder, but when site culture is so focused on scoring points, the result is everyone's too guarded and defensive to appreciate that.

I'd much rather read people randomly gushing about some special interest or rabbit hole they went down, or even just rambling thoughts about whatever, compared to the latest story about the latest thing and discussions where everyone knows where they stand based on their camp. It gets boring.
