The Weekly Standard carries Stanley Kurtz's insightful analysis of the issue of gay marriage in Beyond Gay Marriage.
Among the likeliest effects of gay marriage is to take us down a slippery slope to legalized polygamy and "polyamory" (group marriage). Marriage will be transformed into a variety of relationship contracts, linking two, three, or more individuals (however weakly and temporarily) in every conceivable combination of male and female. A scare scenario? Hardly. The bottom of this slope is visible from where we stand. Advocacy of legalized polygamy is growing. A network of grass-roots organizations seeking legal recognition for group marriage already exists. The cause of legalized group marriage is championed by a powerful faction of family law specialists. Influential legal bodies in both the United States and Canada have presented radical programs of marital reform. Some of these quasi-governmental proposals go so far as to suggest the abolition of marriage. The ideas behind this movement have already achieved surprising influence with a prominent American politician.
He also covers heterosexual polygamy.
Why is state-sanctioned polygamy a problem? The deep reason is that it erodes the ethos of monogamous marriage. Despite the divorce revolution, Americans still take it for granted that marriage means monogamy. The ideal of fidelity may be breached in practice, yet adultery is clearly understood as a transgression against marriage. Legal polygamy would jeopardize that understanding, and that is why polygamy has historically been treated in the West as an offense against society itself.
In most non-Western cultures, marriage is not a union of freely choosing individuals, but an alliance of family groups. The emotional relationship between husband and wife is attenuated and subordinated to the economic and political interests of extended kin. But in our world of freely choosing individuals, extended families fall away, and love and companionship are the only surviving principles on which families can be built. From Thomas Aquinas through Richard Posner, almost every serious observer has granted the incompatibility between polygamy and Western companionate marriage.
Where polygamy works, it does so because the husband and his wives are emotionally distant. Even then, jealousy is a constant danger, averted only by strict rules of seniority or parity in the husband's economic support of his wives. Polygamy is more about those resources than about sex.
Yet in many polygamous societies, even though only 10 or 15 percent of men may actually have multiple wives, there is a widely held belief that men need multiple women. The result is that polygamists are often promiscuous--just not with their own wives. Anthropologist Philip Kilbride reports a Nigerian survey in which, among urban male polygamists, 44 percent said their most recent sexual partners were women other than their wives. For monogamous, married Nigerian men in urban areas, that figure rose to 67 percent. Even though polygamous marriage is less about sex than security, societies that permit polygamy tend to reject the idea of marital fidelity--for everyone, polygamists included.
Gay marriage will also have corrosive effects on hetersexual outlook on marriage as well.
IRONICALLY, the form of gay matrimony that may pose the greatest threat to the institution of marriage involves heterosexuals. A Brigham Young University professor, Alan J. Hawkins, suggests an all-too-likely scenario in which two heterosexuals of the same sex might marry as a way of obtaining financial benefits. Consider the plight of an underemployed and uninsured single mother in her early 30s who sees little real prospect of marriage (to a man) in her future. Suppose she has a good friend, also female and heterosexual, who is single and childless but employed with good spousal benefits. Sooner or later, friends like this are going to start contracting same-sex marriages of convenience. The single mom will get medical and governmental benefits, will share her friend's paycheck, and will gain an additional caretaker for the kids besides. Her friend will gain companionship and a family life. The marriage would obviously be sexually open. And if lightning struck and the right man came along for one of the women, they could always divorce and marry heterosexually.
In a narrow sense, the women and children in this arrangement would be better off. Yet the larger effects of such unions on the institution of marriage would be devastating. At a stroke, marriage would be severed not only from the complementarity of the sexes but also from its connection to romance and sexual exclusivity--and even from the hope of permanence. In Hawkins's words, the proliferation of such arrangements "would turn marriage into the moral equivalent of a Social Security benefit." The effect would be to further diminish the sense that a woman ought to be married to the father of her children. In the aggregate, what we now call out-of-wedlock births would increase. And the connection between marriage and sexual fidelity would be nonexistent.
Hawkins thinks gay marriages of convenience would be contracted in significant numbers--certainly enough to draw the attention of a media eager to tout such unions as the hip, postmodern marriages of the moment. Hawkins also believes that these unions of convenience could begin to undermine marriage's institutional foundations fairly quickly.
In the end, the movement for gay marriage, polygamy, polyamory, and their ilk will be a foot in the door to removing marriage from state-sponsorship to just being a contractual partnership between any number of individuals (and non-humans as well?). It will be to the detriment of both the adults and children involved as well as society in general.
