I agree 100%. my sponsor once told me that I may be the only copy of the big book that people will see.It`s a program of change, and people who practice the program on a daily basis tend to be nicer people.
It`s these people who I try to learn from as I journey through my daily life.
As you say, AA is about attraction rather than promotion. treat people as you would like them to treat you.
After a little while in AA I was fortunate to pick a sponsor who did a lot of service work within AA and who was very much aware of all AAs Guidelines and Traditions which he adhered to and he passed on information of those to me as well as encouraging me to do service work first at group level then Intergroup and Region .Each service position at whatever level the person leaving the position ensured I knew what the position entailed and offered me their experience and guidance and support.Those AA members were great Ambassadors For AA too and when the Traditions were breached or something needed to be put right they didnt sit on the fence and keep their mouth shut but stood up and were counted for the Guidelines and Traditions of AA
As Bill W wrote .AA will not be damaged from outside but can be damaged from within
