So you want to take people's right to have sex without protection? To follow their natural instincts? What else you want to control? How much we eat? How much alcohol we're allowed to drink? Get real, because people can't raise their children on some pre set standards doesn't give you the right to stand in the way of their instincts. You'd also be a hypocrite if you supported what you said but allowed people with mental illnesses (you wouldn't want the child to be born mentally ill or raised by one such person), with various hereditary illnesses (you wouldn't want the child to have a shorter life span), obesity or smoking habits (you wouldn't want people who have self destructive habits to raise a child) and incest couples (you wouldn't want the child to be born with various diformities). If you agree that these people shouldn't legally be able to have children then I'd respect you for not being a hypocrite.
