[Robert] George’s argument is now the official legal defense of the anti-gay marriage movement. “Marriage’s importance,” the GOP House DOMA defenders claim, “is derived from its intrinsic connection to procreation.” The fixation on marriage as a procreative tool also reverberates in the myriad amici filed by gay-marriage opponents. By contrast, pro-gay-marriage amici argue that gays seek to marry “to create a stable foundation for having children, to deepen and enrich their commitment to each other, and to bind their extended families together into a new community.”
In a sense, George is correct: Perry and Windsor are not simply about who gets to marry, but what marriage is. Is it fundamentally rooted in a sex act? Or is it a means of securing two people’s love and commitment to each other and their children? That, as much as any legal doctrine, is the question the court now faces.
