Like most religious cults, AA uses fear, intimidation, and death threats to keep it's flock in check.
"The truth is, that in the life of each AA member, there still lurks a tyrant. His name is alcohol. And his weapons are misery, insanity, and death. No matter how long we may be sober, he always stands at each man's elbow, ever watchful of an opportunity to resume his destruction."
