I think it would be plagued with the same problem that probably led to the hostility from the person in the comment I linked to, bad actors. I recognize that there are a lot of bad actors that enter these conversations and pose “questions” that are really just preludes to attacks, or often intentionally engineered to stoke hostility. I think the solution might be simple, give people the benefit of the doubt until they show they don’t deserve it. But our different perspectives are becoming so tribalistic that opposing views, or even just ignorance of a specific view is viewed as an outright enemy. That has led to people being dismissive of everyone that doesn’t immediately identify themselves as part of the in-group.
I don’t really see how we will ever build a world that is beneficial for everyone if we’re all committed to an “us vs them” perspective. Even without that perspective, IDK how to build that world because it seems now that different groups have drastically different ideas of how things should be. It used to feel like we all kind of wanted the same things, but just disagreed on how to get there. Now it feels like there are groups who want dramatically different outcomes. How does one resolve that type of scenario? Anyways, now I’m getting pretty far off topic. I’ll just stop there.
Maybe a community like you proposed would be a great bridge between groups. It would be so cool if that worked. I know I don’t have the time or patience to run such a group though. Everything online is such a challenge to moderate these days with State level psychological cyber warfare as prevalent as it is now.
