Root Causes, Homosexual Consequences
BTW, I should have added in my long comment above, that I managed to kick "substance abuse" without any 12 Step programs, rehab or the like. Some people need the support that such groups or facilities offer. I have an old friend who became a heroin addict (I never touched that stuff) and it took 6 months at a livein facility to kick it. And he was a religious believer at the time. Different people need different circumstances or kinds of help. What works for one might not work for another. Does that nullify the benefit of different kinds of programs or help, just because some manage to get free from drugs, alcohol or same sex attraction without?
Of course not. As the child of an alcoholic who has worked with the homeless in a wet shelter, I have very little faith in 12 step programs. That's not a popular position, but I stand by it.
But no 12 step program is going to help one "kick" having blue eyes, fix a broken bone, or make one dislike something they genuinely like. I think drug and alcohol use has roots in inherited traits but that is a prediliction--a program. Whether one "activates" that program is where individual will comes in. I don't think one can "will" what turns them on sexually, or else we would have zero infidelity, zero child sexual abuse, etc. (No, I don't believe the urge to molest children is the same thing, I'm merely drawing in all varieties of sexual activity--and I don't for a second believe that there is no sexual component to the urge to rape as some claim.)
