I moderate the Political Forum at BladeForums, and the Christian Knife Enthusiasts Forum at KnifeForums.
Otherwise, I like Ethics, Negotiation, Philosophy, Self-Defense and Martial Arts type of forums.
As helicopter pilot, I used to visit the helicopter pilots forums, but I can't stand those guys.
Anyway, despite the outward impression of knife and gun forums, I have a strong interest in non-violence (I had a problem with violence in the past).
