Re: evolution and homosexuality!
Packyfairy, care to elaborate on how that is ignorant?
IMHO i don't think it is heritable. Its a state of mind picked up from your surroundings. The more you hear about it and the more you see it being accepted the more you gravitate towards it. When a lie is trumpeted so many times it starts to sound like the truth.
As for the human race, gay couples still do adopt kids and lesbian couples give birth using artificial insemination, so its not like there's a risk to the human population if suddenly the whole world decides to go gay. But long before that problem ever surfaces there will be many other unforeseen issues that will arise much sooner.
