What's marriage for, after all? The propagation of voters? A man of politics might see it thus, but he would in fact be seeing nothing at all. That the sexes are made in particular, and complementary, ways is a fundamental truth about the fundamental human institution of marriage. It might just be -- leave the press conferences aside -- that this complementarity serves a higher purpose than mere companionship.
One doesn't have to share a bed with a companion in order to be companionable. A traditional male-female marriage, by contrast, affords the means both of conception and nurture. Not so the union of woman and woman, man and man. If it did, you might suppose humanity would have hit on this piece of wisdom long before Barack Obama, in the run-up to a major election, professed to discover it.
The fundamental truths about us human beings, passed down through the centuries, are best handled delicately, even reluctantly, lest we do them grave injury. To put them up for political bidding is the most disgraceful kind of idea. Philosophers and theologians don't always agree, even on the largest existential matters, but they outrank in moral authority those who peddle their notions for votes. For one thing, the vote peddlers don't discern, they accuse. They don't ponder; they pander. How can we know any such thing? By watching and then weeping.
