Who is to say what is natural and what is not? We are one of the only two species on Earth who can take pleasure from sex. If anything, that makes us the oddballs in the whole food chain. What we choose to do with our lives is not the business of anyone else and to judge those based on how they live their lives is to deprive this world of its variety. Variety is the spice of life afterall and to take it away would make us all a bunch of drones where city life would be as unappealing as licking radioactive slime off a sewer grate.
People have the right to live how they choose and if what we invent allows those who live in contradicition to what is "natural" do what they never could before, then so be it. People want kids, people want houses, people want to live freely. Who are any of you to arbitralily deny anyone children simply because how they live is not "natural?" I\'m sure many of you enjoy sex in a number of different ways with your significant other... does that mean we should burn them all at the stake since what they do is not the natural church goer sex that it should be? Please, this is ludicrous.
As for me donating sperm, that all depends. The parents lifestyle may affect the child, but it would be even more damaging if the parents were abusive...
Coredweller nailed it on the head... The homosexual people I have talked to all say they were just born that way. It had nothing to do with choice or preference at all. They can\'t just turn it off like a switch. We\'re not vulcan afterall.
