AA is not the slogans on the wall.
It's spiritual if you want it to be, or it can be religious if you find that approach to be suitable to whatever position you are taking. AA will let you decide if your alcoholism is a disease or a moral failing or just a symptom of something deeper.
AA is 90 in 90 if you want it to be, or not. AA will let you choose your bottom. You can decide not to focus on tomorrow or if you simply want to enjoy, or deal with, (again, it's your choice) today.
AA doesn't mind if you beat on it or kick it around and spit on it, it still will always be there for you when, or if, you want it... or need it.
It is dumbed down nonsense until you don't want it to be... when you stop drinking and actually read the big book, maybe experience some of it for yourself, talk to someone who has lived it... and if it is still dumbed down nonesense to you... then that's OK too.
