This site had a forum for talking about politics and such for quite a while. It was called the Spin Zone. I did learn things there.
Unfortunately, a handful of bad actors, most of whom generally didn't post in any other areas on the site, caused a lot of trouble. Also, someone who was on the MC will have to chime in, but I believe that well over 90% of reported posts were in the Spin Zone, and it was just taking too much time from a volunteer moderation group to keep up with it, so it was closed.
It's very unfortunate that it's hard to talk to each other any more, and that most communication mediums we have left will tend toward the extremes. Unfortunately, it's not profitable to be the host of those communications, so nobody does it. Facebook is a possible exception, but it seems that enough people like their echo chambers that many have switched to Xwitter, TruthSocial, and other places where they can only hear what they want. Or, they've just unfriended those they disagree with, which also isn't productive.
And that's too bad. I've had some very interesting conversations with my diverse group of friends on Facebook. I have interesting friends... A conversation about gun control gets really interesting when you are friends with a teacher who's also a gun enthusiast. I'm also friends with (at least) three people who have unfortunately had immediate family members murdered. So if I posted something about gun control, it'd get 500+ comments... And I hope some of my friends learned something and listened to people with different experiences.
Sadly, I also had people who decided to unfriend me, so I quit posting political things for the most part. Social media is important to me as a way of keeping up with many distant friends and acquaintances, and I've had some wonderful experiences as a result of social media, so it's not worth it to enter into those discussions.
