It’s only common sense. I mean, having two male or two female parents is hardly a natural setting. Remove the fog of political correctness, and that’s the obvious conclusion.
I can't fathom why gay people - who understand the emotional pain of bullying more than any other group of humans - would possibly do this to a child. When it comes to the rights of children, abortion advocates say that abortion is necessary to spare the child a difficult life (i.e., poor, single parent, drug addled parents, mother was raped, etc); yet gay couples actually fight for the right to bring-up a child in the difficult conditions that surround the gay lifestyle.
Plus, my anecdotal knowledge of the subject has shown that every single gay I personally know suffers from bouts of depression and self-loathing or carries a constant, angry bitterness toward society. I've always looked at them and wondered why they keep removing themselves further from social stability when they are so darn unhappy already.
