In order to come to some kind of determination that changes in the mother's immune system somehow causes her son to be sexually attracted to someone of the same sex would take a whole heap of pretzel logic.

IIRC this theory was mentioned in "Genome: The Autobiography of a Species in 23 Chapters", didn't seem that far of a stretch for a theory. Maybe I should dig the book up and read it again, it's been a couple of years.

Well, if you dig it up, I'd be glad to read about it, but sorry, I can't believe there is a legitimate biological factor that causes sexual attraction.

If you think about it, attractions are all based on external factors and determined by life experiences - how you were brought up, your relationship with other family members, childhood memories both traumatic and happy, etc.

You're never going to convince me that there's some kind of gene that causes one to go va-va-voom when eyeing that special someone. Once you go that route, then you have to say the same for other sexual deviancies. Do you believe that a pedophile has a gene that causes him/her to be attracted to children?
