Hm. Don't know. When I haven't found a thread useful or occasionally even detrimental, I just stay off it (mostly anyway. Sometimes I'm too opinionated for my own good). That way all the AA/non-AA, God/no God stuff doesn't bother me unless I want it to.
But I admit sometimes I'm pretty oblivious to people. I spent a long time putting up an emotional wall, and darned if I'm taking it down now!
