And the only way to have a civil politics forum is to have some professional moderator like dang who can step in and explain the rules to anyone who gets carried away a bit too much. Little by little, the users get educated and start enforcing the rules themselves, either via downvotes, or via actual comments.
Wouldn't that be great? In an age of complete political polarization, to have a sanctuary place on the internet where you can go and exchange thoughtful ideas with considerate peers who may or may not share your political alignment, but treat you with respect.
