Politics seems largely community/self moderated here, it is not outright avoided but purely ideological posts tend to get down voted or ignored. It seems a nice balance and I do not have to tiptoe around accidently triggering people who are ruled by the absolutes of their ideology and derailing a thread.
It results in a community which can be somewhat slack when it comes to the rules, makes everything more conversational which is important for having quality discussion on anything.
