I think there have been studies that have determined that homosexuality cna be caused by hormones being lacking during fetal development i.e. if a boy doesn't get enough testosterone at a certain phase he'll end up gay. It seems to me that the level/amounts missing determine just how gay - from bi-curious gay to Jack McFarland gay. This is just something I heard so I don't know if it's true adn I can't quote the source.

My take - anyone who will provide a good, nuturing home for a child should be allowed to have one. There are plenty of hetero couples that are complete trailer-trash, welfare-aponging losers that don't deserve kids and they get as many as they want. It's a bunch of sh!t.

An interesting note - I have a friend (hetero) who has a twin brother that is gay. I don't think environment had much to do with that one, since they grew up together. Although he spent some time in South America, where they have some kind of ball-grabbing custon.
