It’s Possible: Gays and Lesbians Can Have Happy Marriages by Doug Mainwaring

Striking down man-woman marriage laws on the basis of constitutional discrimination would thus send a message to the same-sex attracted that there is only one choice for them, that man-woman marriage is unattainable, that they are acting against their nature for desiring it, and that pursuing it will be dangerous for them, their spouses, and their children.

But the opposite is true. The man-woman definition of marriage is not an insult; it is an ensign, beckoning to anyone—regardless of sexual orientation—that the union of a man and a woman is of unique significance in light of its procreative power and complementary capacity.

The man-woman definition of marriage—conjugal, complementary marriage—is an ensign not because it is just a good idea, or the best among many. It is a bright ensign because it is the truth, undeniably displayed in nature and in each of our physical beings. We are made male and female, as complements to each other. And when male and female come together, they unite as one flesh. When two males or two females attempt to join together sexually, they remain two males or two females. To base marriage solely on romantic or sexual interests requires averting our minds from easily discernible truth.
