Didn't read the entire thread, only got this far. I'm sure this has been addressed already, as was the OP but I feel the need to reiterate.
I know many people who have long term sobriety in AA. I have a certificate in counseling, and a whole lot of experience on this subject.
AA requires absolutely nothing of anyone lest a desire to stop drinking. A 12 step program is suggested as a way to combat alcholism. The people who follow the 12 steps have a much better success rate than those who don't. Many people get sober and stay sober in AA just by attending meetings. I've seen people die sober and happy with over 30 years off of alcohol, without ever turning their lives over to a "higher power".
While I've heard it said "jokingly" that some people make parking meters, radiators and other such things their higher power, the notion is ridiculous and it doesn't actually happen. The majority of members are relatively intelligient and sane after the alchohol is removed, and well... trust me, it doesn't happen. What some people DO do (that have higher power issues) that want to incorporate the 12 steps into their life is make the group their higher power, or some people use the acronym Good Orderly Direction.
AA doesn't claim to be a cure for alchoholism. AA never had anything to do with courts appointing people to go there. AA never claimed that there aren't other ways for people to recover. As far as things go right now however, AA has the greatest success rate.
One last note for now... if someone is convinced that their negative opinion of AA is what it is, from their experience with a handful of meetings, I urge them to check out different places with an open mind. Every meeting has a different tone, and each group is autonomous which basically means that they run things a little differently. As in the rest of the world, there are some crazies in AA. A sensible person can weed the crazies out and listen to the people who are leading happy productive lives, free from their shackles to alcohol.
