I agree that homosexuality isn't a free choice, no-one's sexuality is in the end, but I do question how anyone can be born gay, or straight for that matter. Isn't it a matter of nurture rather than nature, the interaction with others and the development of sexual feelings as one grows older? It is something that develops over time and it isn't a clear-cut, cast iron thing, where someone's skin colour is an unalterable fact from birth.
Check out the research of Prof. Dick Swaab
, Netherlands Institute for Brain Research, for instance.
He's addressed this matter in exactly the way you describe.
I worked with this guy as an assistant, some fifteen years ago, and believe me he was as surprised about the outcome of some of his experiments as anyone was - and to make things clear, he's NOT attached to any gay movement or anything.
Even more - he was BASHED for it by a small but significant part of my country's gay movement for claiming 'gayness' was rather determined by biological factors than by anything else, even if he himself acclaims environmental influences to play a role as well.
it to be a purely free choice, but alas - science showed the contrary. It is NOT.
Swaab is a highly respected scientific researcher, not just in my country, but throughout the world. Of course NOT with the Jerry Faldwells of this world and other rabid 'believers' - in any
meaning of the word, but that's obvious.
