Two Mothers do not Equal a Father... Two Fathers do not Equal a Mother.
Boys and Girls are being Deliberately Denied one of them in Gay Marriage all for an Attempt at finding some Validation in their Deviant Sexual Choices.
It's really Fucked up.

It's more than just that. I own a ranch and run several different species of critters. Innate to all of them is the protection and care of their own offspring. I'll give you my sheep for an example. They instinctively recognize and bond to their own lambs in a flock and any other lambs that try to approach them they head butt away. They are fiercely protective of their own lambs. Any predator like a dog or fox etc. that comes near their lambs, they will guard them and fight for them as much as they can. Other lambs are left to their own moms. Somehow a ram knows which lambs are his and lambs sired by a rogue ram he will act more distant and hostile towards. It's biological.
There is no denying the strong bonds of the natural biological child of two parents. A woman has the birth and pregnancy to foster this bond. A man sees his own eyes, chin, nose or hair on his infant and warmly regards him as "a chip off the old block". These two people, should they be in love, are the best two people in the world to raise that child. That's why vows implore participants in marriage to stick by each other through thick and thin, to not forsake each other for another. It isn't for their benefit. It is for their children's benefit that this is so. Marriage is about children. It is society's insurance that children [future adult members] receive the best possible upbringing as a rule.
A society has a deeply vested interest in preserving this situation. Gays don't fit the bill. Especially their defended reverence for a man who raped, habitually, teen orphaned boys on drugs.
