As someone who has caught many a resentment against people in AA, I would say this has not been my experience. I would advise to keep looking for other meetings and another group.
A man with 50+ years came and spoke at our group last week. He said, "it doesn't matter a bit how far away from my last drink I am; all that matters is how far away I am from my next one."
And I have found that the minority of people who bray, thump, and preach the loudest have been people with a history of relapse (my observation). So I listen even harder even though my pride and will gets all puffed up when they start on their tirades directed against no one in particular (or maybe themselves).
