You can question any couple's ability and fitness to raise children, but not solely based on sexual orientation. No one bothered to tell my parents that it really isn't a good idea to bring babies into the world when you're a herion addicted, alcoholic, narcissistic pair of people who can't even take care of themselves. I would rather some "different" form of parents that had the ability to put their child before their own selfish, self destructive needs, and raise them with love and security and an acceptance of who they are no matter their orientation. But hey, that's just me.
