Similar sentiments are probably being expressed in AA meetings right now, although perhaps more politely. Truthfully, in AA as elsewhere most people are probably too self-absorbed to really care what your "higher power" is.
There's a paradox. When your brain has been rewired by a substance addiction it's very hard to think your way out of that addiction. Your brain thinks it needs this stuff and it may be right, in the moment. Your conscious mind may be very invested in preserving the status quo. So, many of us have to come at it from a different angle, to find some aspect of ourselves beyond our ordinary conscious will. With me, I discovered more or less by accident that prayer "worked" in a situation where I was going insane with fear and that was pretty much all I could do. It did not change external reality but it changed something in me.
I routinely stick up for AA, because I know in a couple of hours I could be in a room with 30 people, relaxing during the opening rituals and absorbing what people share about their own experience. Maybe I come back to that meeting, maybe I don't. Strictly up to me. Making people attend is probably counterproductive and may be dangerous. I thought that practice was on the wane.
