There’s probably a better community for asking this, but I haven’t been able to find that one either.
What I’m looking for is a place to discuss ideas that encourages good-faith conversation, staying on topic, and being decent to one another - while actively discouraging mean-spirited, facetious, or bad-faith responses that focus on criticizing the person asking the question rather than engaging with the substance of it. And by “discouraging,” I mean active moderation with very low tolerance for that kind of commentary.
I haven’t found any. Anything of that sort would need heavy handed and laborious moderation and would lend itself to quite a lot of bias from moderators. Your best bet is to do this sort of thing locally with a small group of friends (or internet friends).
Based on my experience trying to have deep and sometimes difficult conversations here, I’ve come to believe that if such a community did exist and gained even a bit of popularity, it would likely result in a large number of the currently active users here getting themselves banned from it. In the end, it might just be a small group of users left - the ones actually interested in playing fair. I don’t necessarily see that as a bad thing, though. You really don’t need that many people to have insightful discussions. Often, even one person is enough, as long as they’re approaching it in good faith.
Moderation would definitely be an issue, though. Dealing with the worst offenders is easy - it’s the gray areas that are challenging. The space wouldn’t just need to be heavily moderated; that same standard would also need to apply to the moderators themselves.
