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.
