Discuss the issues all you want, but do not make it personal.
AA has a singleness of purpose which is to help the alcoholic that still suffers. (Trad. 5)
AA is based on attraction, rather than promotion. (Trad. 11)
Finally I am not attracted by the self-promotion and criticism of AA, which my family and I credit for saving my life.
Same for the Catholic priest who conducted my intervention. He later left the priesthood, but works professionally in recovery.
He wrote the book he is promoting here for the second time. If his credibility is off limits then there is no place for this thread here on this board at all.
