Marriage is what marriage is. Marriage existed before there was a government. It's like, you know, handing up this and saying this glass of water is a glass of beer. Well, you can call it a glass of beer, but it's not a glass of beer. It's a glass of water. And water is what water is. Marriage is what marriage is.
