I can imagine a useful political forum on here that followed a version of the mod rules from this site.
https://www.reddit.com/r/changemyview/
Explain the reasoning behind your view, not just what that view is (500+ characters required).
No meta posts.
Only post if you are willing to have a conversation with those who reply to you.
Direct responses to a post must challenge at least one aspect of OP’s stated view (however minor), or ask a clarifying question.
Don't be rude or hostile to other users.
Refrain from accusing OP or anyone else of being unwilling to change their view.
No low effort comments.
I would add,
Cite sources to back up factual claims.
Before someone posts that I hardly set an example of following these rules right now I wholeheartedly agree which is why we need them. I fall victim to the screaming mob mentality too often.
