But for me, this place is unique - fellow recovering drunks who are sober, but who don't and won't accept the concept of god (in any meaningful sense) but who can chat and support each other
Actually I am a believer (not a churchgoer). I support first and foremost sobriety, no matter how you find it. I also respect everyone's beliefs, or lack thereof - something you don't always see in an AA meeting, to be sure.
