"I realized that the argument in support of gay marriage is predicated on one audaciously bald-faced lie: the lie that same-sex relationships are inherently equal to heterosexual relationships. It only takes a moment of objective thought to realize that the union of two men or two women is a drastically different arrangement than the union of a man and a woman. It’s about time we realize this very basic truth and stop pretending that all relationships are created equal.
At its core, the institution of marriage is all about creating and sustaining families. Over thousands of years of human civilization, the brightest minds have been unable to come up with a successful alternative. Yet in our hubris we assume we know better. Americans need to realize that same-sex relationships will never be equal to traditional marriages."
You have probably spotted that I didn't actually write this argument (which I agree with) since it is obviously written in an American context.
What you may not have spotted is the provenance from which the argument comes. Read the whole piece here ... you might be surprised :)
