Changing the program of AA is beyond the scope of these forums. The debate can and has gone on for years. This forum is for personal recovery. The original thread starter was asking for advice because he/she was going to attend an AA meeting. Bringing up everything that is wrong with AA goes beyond personal experience and beyond the topic of this thread.
The forums are intended for personal recovery. We are not going to change the program of AA on these forums so the discussion in general terms does not have a solution here.
Atheists and others have voiced their frustration against AA because there are no other options or because they think AA is harmful to others. Again that is beyond the scope of the intended purpose of these forums unless you are sharing your personal experience and seeking solutions or offering solutions that can help others who are posting on these forums.
There are some options.
Start a LifeRing Recovery Meeting

Start a SMART RecoveryR Meeting

Here is a list of some AA meetings for agnostics and atheists. Start your own.

If you want to debate about whats wrong with AA there are other forums for that purpose. If you want to change the program of AA you will need to take that up with them. If you want to change the attitude of everyone who attends AA I have no suggestions.
