If you happen to be an athiest a higher power doesn't exist either. The whole idea that a higher power can be anything (even a door knob, I was told... WTH?) seems a bit like trickery.
I've been attending an agnostics meeting and a couple of weeks ago our local AA president (if that is the correct title) came to visit and told the facilitator that he shouldn't call it an AA meeting because God has been removed from the equation. That really bothered me. We have enough religious exclusion in the United States in our politics.
Again, AA should be about recovery, not our religious beliefs.
