I don't know that it's a "hang-up" particularly, but it just has a number of practices that make me uncomfortable. The powerlessness aspect, the focus on a higher power, while at the same time saying it isn't a religious program. Several studies show that it seems to have an abysmal success rate. It just feels a bit cultish to me. Please understand that I am not attacking the program; it's obviously successful for a lot of people. It helps me, too. I just have a mental componant that won't allow me to be assimilated into the whole AA culture as thoroughly as some are. I wish I could, quite frankly.
