The stigma certainly does need to be crushed dsmaxis.
I can remember many years ago when, by chance, a bumped into a man I knew from AA, and it was clear that he was having a psychotic episode. He had been told by members to stop taking his meds, and that all he needed to do was his 4th Step! I had to have him hospitalised.
I thought that sort of thinking was no longer around AA and sorry that it's happened to you.
My brother no longer goes to NA because of the very stigma you describe.
AA is not the venue to have religious "arguments" dsmaxis10, it's a place of support for people who are trying to get sober. Arguments on religion are not what it's about.
Really glad you have all the other supports in place. Supports that are devoted to your own specific needs and stigma free.
