Chadbang, you are doing the right thing. If a particular forum or thread topic bothers you, simply ignore it. I'm not a big believer in cables and tweaks, and reading and/or participating in arguments about it are pointless and frustrating to me ... so I simply avoid the cables and tweaks forum.
The Outside forum was originally started when Head-Fi was a much smaller community to satisfy some member's desire to discuss topics which were not only not audio related, but were considered too "hot" for general discussion. There are a lot of intelligent people visiting Head-fi, and some of them do enjoy discussing politics, religion, and other controversial topics. Each to their own. Let's face it, in the big picture, many of these topics are ( or should be) much more important in a person's life than whether or not a certain headphone has muddy bass.
As long as members control their tempers, don't troll, don't make things personal and refrain from making personal attacks, don't intentionally insult others, and stick to the thread's topic, the Outside forum can be quite enlightening no matter which side of a discussion one may take. A lot of quality information and thought gets presented there. To prevent it from becoming an ongoing brawl, we've had to moderate a little more harshly than we'd like at times, but it's been decided that is better ( for the time being at least) than completely denying the option of more worldly discussions from those who enjoy participating. The Outside forum gives those who are interested a unique opportunity to discuss these topics with people of all ages and from all around the world. I think we're lucky to be offered this opportunity to have access to such diverse insight.
For those who aren't interested, or prefer to avoid debate and confrontation, follow Chadbang's lead and simply avoid Outside. But don't think that gets you completely off the hook .... I've seen some fairly heated arguments regarding muddy bass as well.
