Hi Phil,
This might be a bit abrupt as a greeting 
, though I completely understand your point of view. I’d start by asking myself: why would you stay at AA meetings? Just to tell newcomers to go home? Basically, you’d be turning people away just because you disagree. How would that help you?
If I were you, I’d ask myself this: is it necessary to give advice to people who haven’t given you what you’re looking for?
It’s funny, I just wrote something about this in my open diary today. I’ll link it for you. If you’re interested, feel free to check it out!
