First, I've resigned my membership to several online forums. It's a bad sign when every visit to a given forum makes you feel worse than you did before said visit, and when the obvious 'edition wars' trolling obscures any useful content to such a degree that you have to use the forum search function to find the latter.
Second, I've removed links to the forums mentioned above and several others from my own web page, as I'm more than a little reluctant to recommend forums that are currently thick with the hate to anybody else. Some of those links will probably be re-posted when/if the heat dies down, though until that happens, I don't feel comfortable saying "Hey! Post over here!"
Third, I've also started looking at games other than D&D 3x or 4e for actual play, lately. For instance, I play in a Dark Heresy game on Tuesdays, and I'm leaning toward starting a Risus game soon, as well as a Holmes BD&D game (the Borderlands thing in my .sig). I really have no desire to stumble into the real-life equivalent of the forum arguments that I've seen.
