Really Joh-née? Is biology mandated? Is conception mandated, or does it happen when men AND women have sex. You really should work on fretting your G.E.D. Let's keep this simple. Sex makes babies, even ones who grow up and post on Internet forum sites under the name "Jonah1". Human societies throughout history have understood this. Marriage developed as a means of regulating that. Are you with me so far? Good. You are smarter than u seem. This would also explain why there's never been a cross time cross cultural, with a sustained deep historical foundation of SSM, male or female, certainly not in western civilization, if not around the world. Granted there are scattered historical examples of various societies recognizing same sex relationships in some form, although most of those seem to be male only.<quoted text>
What "function" are you referring to KiMMy? Is this "function" mandated? Or simply more of your pseudo psycho babble?!
The bottom line is, at its core, marriage serves a vital function within society. It links mean and women to each other, and by extension to the products of their union, children. We tamper with marriage at are own peril.
