Of course, in certain Catholic circles, this particular argument, as outlined by Wolfson, is basically the "Natural Law" argument – one that's vigorously championed by the clerical caste and by folks like Janet Smith.
Following is an excerpt from chapter four of Evan Wolfson's Why Marriage Matters.
If you go to any of the hundreds of fundamentalist Web sites on the Internet today, you have a good chance of coming across a list of talking points against “same-sex marriage.” One such script, put together by the Christian radio show Point of View, gives thirteen reasons why listeners should be opposed to gay couples’ freedom to marry. High on the list is a lesson in “basic biology.” According to Point of View’s script, anti-marriage-equality activists are supposed to say, “Homosexual relations deny the self-evident truth that male and female bodies complement each other. Human sexuality and procreation is based upon a man and a woman coming together as one flesh. Marriage between a man and a woman promotes procreation and makes intimate sexual activity orderly and socially accountable."
. . . At first glance, the “basic biology” argument seems to make some sense. After all, it doesn’t take more than a fourth-grade health class education to know that men’s and women’s bodies in some sense “compliment each other” and that when a man and a woman come “together as one flesh” it often leads to procreation.
. . . Because the “basic biology” argument just seems so, well, basic, I understand why some people want to stop right there. But, as I’m sure many of you have already realized, the overstated link between procreation and marriage actually doesn’t explain why we bar same-sex couples (and same-sex couples alone) from marriage as it now exists under law and in our society. In fact, once you scratch the surface of this argument – which is actually more of a gut feeling than a thought-out rationale – you can see that it’s riddled with holes. And thankfully, these are holes that the justices in Hawaii, Vermont, and Massachusetts saw right through.
. . . In the Hawaii freedom-to-marry case that Dan Foley and I litigated, Judge Kevin Chang wrote:
In Hawaii, and elsewhere, people marry for a variety of reasons including, but not limited to the following: (1) having or raising children; (2) stability and commitment; (3) emotional closeness; (4) intimacy and monogamy; (5) the establishment of a framework for a long-term relationships; (6) personal significance; (7) recognition by society; and (8) certain legal and economic protections, benefits and obligations.
“Gay men and lesbian women,” the judge found, “share this same mix of reasons for wanting to be able to marry,” a mix that may including having, or caring for, one’s kids, but often does not, and that for many couples turns on other important aspects of marriage.
In Vermont, Chief Justice Jeffrey Amestoy seemed to find it hard to take the state’s “procreation” argument seriously. If Vermont truly based a couple’s competency to marry on that couple’s ability to procreate, he suggested, state officials might want to take a second look at some of the marriage licenses they have been issuing.
It is . . . undisputed that many opposite-sex couples marry for reasons unrelated to procreation, that some of these couples never intend to have children, and that others are incapable of having children. Therefore, if the purpose of the statutory exclusion of same-sex couples is to “further the link between procreation and child rearing,” it is significantly under-inclusive. The law extends the benefits and protections of marriage to many persons with no logical connection to the stated governmental goal.
And in Massachusetts, Chief Justice Margaret Marshall didn’t even wait to write the court’s decision in the case before letting the state’s attorneys know what she thought about their use of the “promotion of procreation” as Massachusetts’ justification for excluding gay couples from marriage.
“I think it would be a stretch to say it was for procreation,” she said to the state’s lawyers during the oral argument. “The State is free to say, for example, after a heterosexual couple has been married for ten years and has produced no children, unless there is evidence that both are infertile, that they should be divorced so that thy can be free to marry to try and procreate with another couple?” Despite the asserted link between marriage and procreation put forward to justify excluding gay couples, the state refused to apply any such link to heterosexuals “For the State to draw the line that way would be an impermissible intrusion into the private lives of the people involved,” the assistant attorney general replied (giving no similar weight to the intrusiveness of denying gay people the right to marry and make their own parenting and personal choices like non-gay couples).
Chief Justice Marshall then pointed out that Massachusetts (like Vermont) not only allows non-procreative couples to marry and stay married, but also permits gay parents to adopt, has many parents who conceived their children through alternative insemination and other means, and has a strong public policy of supporting kids, no matter h their parents are or what their family configuration is.
Indeed, even U.S. Supreme Court Justice Antonin Scalia, hardly a proponent of equal rights for gay men and lesbians, wrote in his 2003 dissent to Lawrence v. Texas that the promotion of procreation is a very weak argument for maintaining bans on gay people’s freedom to marry. “If moral disapprobation of homosexual conduct is ‘no state interest’ for purposes of proscribing [private adult sex],” Scalia wrote, “what justification could there possibly be for denying the benefits of marriage to homosexual couples? Surely not the encourage of procreation, since the sterile and the elderly are allowed to marry.”
. . . But now let’s put these constitutional, legal, and historical understandings of marriage and love aside for a moment and instead focus on some of the commonsense reasons why the procreation argument doesn’t work to explain or justify the denial of gay people’s freedom to marry. First there is the point raised by Vermont’s Chief Justice Amestoy and by U.S. Supreme Court Justice Scalia: No state requires that non-gay couples prove that they can procreate – or promise that they will procreate – before issuing them a marriage license. Indeed, no state requires as a condition of a valid marriage that a couple promises to even engage in sexual intercourse, which would be required for traditional procreation.
And when states issue marriage licenses, none of them come with a “sunset provision,” whereby a couple has two or three years to produce a child or the marriage expires. Just imagine how such a law could put millions of marriages in jeopardy.
. . . Every U.S. state routinely issues marriage licenses to elderly, sterile, and even impotent couples. No state requires them to procreate or to raise children; states recognize that these couples have many other reasons for wanting to marry, including, yes, love, adult companionship, mutual caring and support, and personal commitment.
Meanwhile, every state also recognizes that these and other couples can, and very often do, become parents through adoption or any of a number of other approaches to child-bearing, including donor insemination and surrogacy. The “basic biology” argument ignores that gay and lesbian couples do have, and will continue to have, children by these same means.
