That's not generally what happens. There have been numerous studies that support the hypothesis that homosexuality is the result family dynamics... the most common being that male homosexuals were raised by a domineering mother and a weak father who never spent time with his boy whereas female homosexuals are the result of a dysfunctional mother-daughter relationship. If this backdrop is present when perverted circumstances arise during sexually formative years, the result of a sexually perverted individual can almost be predicted. Over the years, I have met a number of women who claimed to be lesbians and heard their stories and it seemed that all had a common denominator of sexual abuse at a young age. One day I met a young lady who told me she was a lesbian to which I asked her "so at what age was it when your mother's boyfriend started sexually abusing you?" I knew nothing about this woman's history or her parent's marital status so my question was going way out on a limb... but she replied "I was 12." The simple explanation here is that what is referred to as lesbianism was triggered by a disgust, hatred, fear, rejection of all men based on perhaps what just one person did... but in a sense going back further, the root of it all had to do with the fact that the absence of parents with a healthy relationship created the circumstances. Are there homosexuals who came from a family background which was ideal or as close to ideal as possible? Sure... but those are far and away a minute exception and it may just be that there were serious problems, they just happened to be hidden.
I have done quite a bit of research on the root cause of homosexuality over the last couple of years, mostly to satisfy my own need to refute the “born that way” claim because that just didn’t make sense to me. I have read exact cases of what you are talking about. There are also plenty of people who site situations of bullying when they were a child. Weak, late developing children are a prime target for this from classmates. Without an adult role model who is aware of the danger and knows the signs to watch for, the kid has no one to turn to for guidance. Combine that with our destructive mainstream cultural attitude that being gay is somehow desirable and it is no wonder that we have confused people sliding into that dangerous lifestyle.
Dr. Joseph Nicolosi was an amazing, positive force for good in the area helping homosexuals who want to heal and live normal, heterosexual lives. He, unfortunately, passed this spring from the flu, but he had a team of therapists he’d personally trained who are carrying on his work. I hope that one of them will pick up the torch of his research. If you aren’t aware of his work, his website is still active and there are many articles that he has written that give a clear picture of homosexuality as the disease it is.
