The late Richard John Neuhaus once articulated a principle that he presumed to call Neuhaus’ Law: “Where orthodoxy is optional, orthodoxy will sooner or later be proscribed.” Over at Public Discourse, Robert P. George offers what I take to be an instance of this law, namely, the “grand bargain” between proponents and opponents of same-sex marriage:

Since most liberals and even some conservatives, it seems, apparently have no understanding at all of the conjugal conception of marriage as a one-flesh union—not even enough of a grasp to consciously consider and reject it—they uncritically conceive marriage as sexual-romantic domestic partnership, as if it just couldn’t possibly be anything else. This is despite the fact that the conjugal conception has historically been embodied in our marriage laws, and explains their content (not just the requirement of spousal sexual complementarity, but also rules concerning consummation and annulability, norms of monogamy and sexual exclusivity, and the pledge of permanence of commitment) in ways that the sexual-romantic domestic partnership conception simply cannot. Still, having adopted the sexual-romantic domestic partnership idea, and seeing no alternative possible conception of marriage, they assume—and it is just that, an assumption, and a gratuitous one—that no actual reason exists for regarding sexual reproductive complementarity as integral to marriage. After all, two men or two women can have a romantic interest in each other, live together in a sexual partnership, care for each other, and so forth. So why can’t they be married? Those who think otherwise, having no rational basis, discriminate invidiously. By the same token, if two men or two women can be married, why can’t three or more people, irrespective of sex, in polyamorous “triads,” “quadrads,” etc.? Since no reason supports the idea of marriage as a male-female union or a partnership of two persons and not more, the motive of those insisting on these other “traditional” norms must also be a dark and irrational one.

Thus, advocates of redefinition are increasingly open in saying that they do not see these disputes about sex and marriage as honest disagreements among reasonable people of goodwill. They are, rather, battles between the forces of reason, enlightenment, and equality—those who would “expand the circle of inclusion”—on one side, and those of ignorance, bigotry, and discrimination—those who would exclude people out of “animus”—on the other. The “excluders” are to be treated just as racists are treated—since they are the equivalent of racists. Of course, we (in the United States, at least) don’t put racists in jail for expressing their opinions—we respect the First Amendment; but we don’t hesitate to stigmatize them and impose various forms of social and even civil disability upon them and their institutions. In the name of “marriage equality” and “non-discrimination,” liberty—especially religious liberty and the liberty of conscience—and genuine equality are undermined.

The fundamental error made by some supporters of conjugal marriage was and is, I believe, to imagine that a grand bargain could be struck with their opponents: “We will accept the legal redefinition of marriage; you will respect our right to act on our consciences without penalty, discrimination, or civil disabilities of any type. Same-sex partners will get marriage licenses, but no one will be forced for any reason to recognize those marriages or suffer discrimination or disabilities for declining to recognize them.” There was never any hope of such a bargain being accepted. Perhaps parts of such a bargain would be accepted by liberal forces temporarily for strategic or tactical reasons, as part of the political project of getting marriage redefined; but guarantees of religious liberty and non-discrimination for people who cannot in conscience accept same-sex marriage could then be eroded and eventually removed. After all, “full equality” requires that no quarter be given to the “bigots” who want to engage in “discrimination” (people with a “separate but equal” mindset) in the name of their retrograde religious beliefs. “Dignitarian” harm must be opposed as resolutely as more palpable forms of harm.
