Here’s a long and interesting article on the scientific research into what causes homosexuality. You may notice that no one seems to think that exposure to hormones in food consumed in childhood has anything to do with it. But note this bit especially:
The cases of children born with disorders of “sexual differentiation” offer insight. William Reiner, a psychiatrist and urologist with the University of Oklahoma, has evaluated more than a hundred of these cases. For decades, the standard medical response to boys born with severely inadequate penises (or none at all) was to castrate the boy and have his parents raise him as a girl. But Reiner has found that nurture – even when it involves surgery soon after birth – cannot trump nature. Of the boys with inadequate penises who were raised as girls, he says, “I haven’t found one who is sexually attracted to males.” The majority of them have transitioned back to being males and report being attracted to females.
According to Rutz’s cracked theory, all these “girls” needed was plenty of soy milk and they would have grown up to be well-adjusted heterosexual women. Somehow, I think the hormonal effect of having one’s testicles removed at birth is greater than that of consuming soy.
