Some of the folks I meet at AA meetings rub me the wrong way. Same is true at my work and my church and any other social group I affiliate with. To me the issue is what is the overall net effect of the group on my serenity. If it's positive I stay and if it's negative I leave. I have never found a group of 100% positive people in any aspect of my life so I don't expect perfection from any group including AA. For me there is more positive energy than negative energy in my local AA meetings so I keep coming back.
