I thought that todays (August 29th) AA Daily Reflection might be pertinent to this thread...
I CHOOSE ANONYMITY
We are sure that humility, expressed by anonymity, is the greatest safeguard that Alcoholics Anonymous can ever have.
— TWELVE STEPS AND TWELVE TRADITIONS, p. 187
Since there are no rules in A.A. I place myself where I want to be, and so I choose anonymity. I want my God to use me, humbly, as one of His tools in this program. Sacrifice is the art of giving of myself freely, allowing humility to replace my ego. With sobriety, I suppress that urge to cry out to the world, "I am a member of A.A." and I experience inner joy and peace. I let people see the changes in me and hope they will ask what happened to me. I place the principles of spirituality ahead of judging, fault-finding, and criticism. I want love and caring in my group, so I can grow.
I was told by an old-timer that my program relies on me being honest with myself, and not being dishonest with others (but also not necessarily telling people things they have no need to know or business knowing). He told me to never put myself in a vulnerable position in my career, because he'd seen others do that, and when people turned against them; gossiped; or they got treated with undue suspicion, this was a threat to their sobriety. That said, my boss knows (in confidence) that I am a member of AA, but that was because she put herself out to help me, and got me counselling, etc. when she was really worried about my well-being. I already knew her very well before making the decision to confide in her. A few colleagues who I consider to be friends first and foremost also know, but again, I would not have confided unless I trusted them.
