It seems to me we have enough examples of men beating their wives black and blue, of women poisoning their husbands, of drunken and drugged incompetents leaving their toddlers to fend for themselves for days at a time, that any notion of the sanctity of the institution of marriage based on blessed bonding of a man and a woman should have been abandoned a long time ago. Hell, you need a license to drive an automobile, but any pair of idiots with differing and functional genitals can conceive a child, regardless of whether or not they have the first idea of how to raise it.

I say if two people love each other enough to want to spend the rest of their lives together and they think they have the strength to do so, let them. If any two people, or any one person, is enough of an adult to take care of children properly, let them have children. I'm not gay, but I care less if someone else is, as long as they treat their mate, their children, and the rest of the freaking world with a modicum of tolerance, respect, and care.
