I was taught years ago that gay people are gay because they want to be. But now I believe quite differently. I believe they're born that way, and so they can't change. There is a grey area of bi-sexuals who can swing both ways, but they are rare in their ability to choose.
As for child molesters. I was taught that they can be rehabilitated. But now I believe quite differently. I believe they're born that way, and so they can't change either. As for the greater prevalence in offences found in men and fewer offences in women, I'm of the opinion that the reason is that most men in general (no matter what their orientation) have a harder time abstaining than women do, and also have an odd thread of violence and forcefulness running through their sexual wiring that most women lack.
Outside of a miracle of God, I can't see a child molester ever changing. Might as well ask a gay man not to be gay anymore.
I think mandatory medication of hormone-reducing drugs should be sentenced to any man (or woman) guilty of this crime. And I also think voluntary castration/ovary removal is a great solution that should be afforded to any man or woman who seeks to be rid of these desires permanently.
