<< that doesn't mean anything, just because the family is normal doesn't mean that there weren't other "un normal" people that came in contact with the two boys. i doubt the genetic influence is strong enough to be solely reponsible for two brothers to be gay. if this were true, hypothetically, if you forced them to have sex with women, i would expect the offspring to be gay. but this is doubtful, imho. >>
I don't mean to say that it's purely genetic. I just don't think that the way a child is raised has as much an influence as some people suggest. And by that, I mean life in the home. Obviously a child will be influenced by certain things, but parents are (I think, anyway), not largely responsible for homosexuality.
