I'm glad you posted the video; it could be helpful for many people. I'm a complete non-theist in the Hitchens/Dennett/Dawkins/Harris mold. When I finally got disgusted enough with my drinking to do something about it I was prepared to do AA. But I never got that far, because I discovered AVRT. My last drink was seven months ago almost to the day. So far, I have no reason to consider AA, but I'm a big believer in doing whatever it takes to quit. If AA works for you, awesome! Do whatever you need to do to quit.
But atheism is a huge part of my self identity. Or rather, a naturalistic worldview is important to me. I'm a Bright and a non-drinker!
