I have to say zaraki, that the entire influence of sexual orientation isn't solely based on that of your parents. By the time you reach the age of puberty, you've likely spent as much time under the influence of your parents as you have to those in the outside world. The concept of sex isn't developed until latter years of childhood. And even then it's often heard about more on the playground then it is from the parents. The numerous social influences a child will encounter can easily outweigh those of any parent(s). It seems you're not taking these and many other factors into account. If anything you can argue that homosexuality is a defect of genetics, or faulty chromosomes. that chemical X is being replaced by chemical Y when the brain does it's work. That their naturally inhabited response to reproduction is confused. Though all these things can be argued in opposition to those who are straight. You can choose what to eat when your body tells you you're hungry. But do you choose what makes you salivate? You can choose what will entertain you when you're bored. But do you choose what makes you laugh and cry? You can choose to have sex with a man or a woman when you're horny. But which will make you cum?
Analog's underwear are digital. right now they're set to inverse 1 (I think that means they're on my head).
