AA does not consider alcoholism to be a moral failing. In fact, it's just the opposite. The BB states we can have moral convictions galore, and it still won't help us overcome alcoholism.
My character defects are the same as everyone else. It's just that those defects keep me blocked off from a desperately needed power. No big deal for a non-alkie; they can get by just fine with those defects. But for an alkie like me, whose problem is lack of power and whose only hope is the maintenance and growth of a spiritual connection, those defects can be deadly.
There are a lot of opinions and ideas on what AA is and what AA is not put out there by a lot of people with very little experience in AA. The BB states clearly what AA is. Better yet, take the Steps and have your own experience with AA. Then you'll know exactly what it is.
