In the name of “marriage equality” and 
“non-discrimination,” liberty—especially religious liberty and the 
liberty of conscience—and genuine equality are undermined.
It was only yesterday, was it not, that we were 
being assured that the redefinition of marriage to include same-sex 
partnerships would have no impact on persons and institutions that hold 
to the traditional view of marriage as a conjugal union? Such persons 
and institutions would simply be untouched by the change. It won’t 
affect your marriage or your life, we were told, if the law recognizes 
Henry and Herman or Sally and Sheila as “married.”
Those offering these assurances were also claiming that the 
redefinition of marriage would have no impact on the public 
understanding of marriage as a monogamous and sexually exclusive 
partnership. No one, they insisted, wanted to alter those traditional 
marital norms. On the contrary, the redefinition of marriage would 
promote and spread those norms more broadly.
When some of us warned that all of this was nonsense, and pointed out
 the myriad ways that Catholics, Evangelicals, Mormons, Eastern Orthodox
 Christians, Orthodox Jews, Muslims, and others would be affected, and 
their opportunities and liberties restricted, the proponents of marriage
 redefinition accused us of “fearmongering.” When we observed that 
reducing marriage to a merely emotional union (which is what happens 
when sexual reproductive complementarity is banished from the 
definition) removes all principled grounds for understanding marriage as
 a sexually exclusive and faithful union of two persons, and not an 
“open” partnership or a relationship of three or more persons in a 
polyamorous sexual ensemble, we were charged with invalid slippery-slope
 reasoning. Remember?
No one, they assured us, would require Catholic or other foster care 
and adoption services to place children in same-sex headed households. 
No one, they said, would require religiously affiliated schools and 
social-service agencies to treat same-sex partners as spouses, or impose
 penalties or disabilities on those that dissent. No one would be fired 
from his or her job (or suffer employment discrimination) for voicing 
support for conjugal marriage or criticizing same-sex sexual conduct and
 relationships. And no one was proposing to recognize polyamorous 
relationships or normalize “open marriages,” nor would redefinition 
undermine the norms of sexual exclusivity and monogamy in theory or 
practice.
That was then; this is now.
I must say, though, that I still can’t fathom why anybody believed 
any of it—even then. The whole argument was and is that the idea of 
marriage as the union of husband and wife lacks a rational basis and 
amounts to nothing more than “bigotry.” Therefore, no reasonable person 
of goodwill can dissent from the liberal position on sex and marriage, 
any more than a reasonable person of goodwill could support racial 
segregation and subordination. And this, because marriage, according to 
the redefiners, consists principally of the emotional union of people 
committed to mutual affection and care. Any distinctions beyond this one
 they condemn as baseless.
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.
As legal scholar Robert Vischer has observed, “The tension between 
religious liberty and gay rights is a thorny problem that will continue 
to crop up in our policy debates for the foreseeable future. Dismissing 
religious liberty concerns as the progeny of a ‘separate but equal’ 
mindset does not bode well for the future course of those debates.” But 
there is, in my opinion, no chance—no chance—of persuading 
champions of sexual liberation (and it should be clear by now that this 
is the cause they serve), that they should respect, or permit the law to
 respect, the conscience rights of those with whom they disagree. Look 
at it from their point of view: Why should we permit “full equality” to 
be trumped by bigotry? Why should we respect religions and religious 
institutions that are “incubators of homophobia”? Bigotry, religiously 
based or not, must be smashed and eradicated. The law should certainly 
not give it recognition or lend it any standing or dignity.
The lesson, it seems to me, for those of us who believe that the 
conjugal conception of marriage is true and good, and who wish to 
protect the rights of our faithful and of our institutions to honor that
 belief in carrying out their vocations and missions, is that there is 
no alternative to winning the battle in the public square over the legal
 definition of marriage. The “grand bargain” is an illusion we should 
dismiss from our minds.
Of course, with sexual liberalism now so powerfully entrenched in the
 established institutions of the elite sector of our culture (and, let 
us not kid ourselves, fully embraced by the President of the United 
States and the leadership of the Democratic Party), some view the 
defense of marriage as a lost cause. I think that is another mistake—one
 that sexual liberals have every reason to encourage their opponents to 
make, and ample resources to promote. We’ve all heard the argument (or 
taunt): “The acceptance of same-sex marriage on a national scale is 
inevitable. It’s a done deal. You had better get on the right side of 
history, lest you be remembered in the company of Orval Faubus.”
Of course, this is what we were told about a “woman’s right” to 
abortion in the mid-’70s. But it didn’t turn out that way. A greater 
percentage of Americans are pro-life today than in the 1970s, and young 
people are more pro-life than people of their parents’ generation. The 
idea promoted by the abortion lobby when their cause seemed to be a 
juggernaut—that “the American people will inevitably accept abortion as a
 matter of women’s rights and social hygiene”—proved spectacularly 
false.
Or, speaking of “social hygiene,” think back to the 1920s and ’30s 
when eugenics was embraced by the elite institutions of American 
society—from the wealthy philanthropic foundations, to the mainline 
Protestant denominations, to the Supreme Court of the United States. 
Affluent, sophisticated, “right-minded” people were all on board with 
the eugenics program. It, too, seemed like a juggernaut. Only those 
retrograde Catholics, joined by some other backward religious folk, 
resisted; and the thought was that the back of their resistance would 
soon be broken by the sheer rationality of the eugenics idea. 
The eugenicists were certain that their adversaries were on “the wrong 
side of history.” The full acceptance of eugenics was “inevitable.” But,
 of course, things didn’t quite turn out that way.
Note that my point here is not to say or imply that 
redefining marriage is morally just like abortion or eugenics. There are
 obvious and important differences. My point is about the claim by 
progressives and some others in each case that the triumph of the cause 
was “inevitable,” and that those who declined to go along were “against 
progress” and had placed themselves on the “wrong side of history.”
Does that mean that the reverse is true, that the conjugal conception
 of marriage will inevitably prevail in law and culture? No. There is 
nothing inevitable in this domain. As the left-wing—but 
anti-Hegelian—Brazilian legal theorist Roberto Unger used to preach to 
us in courses at Harvard Law School, the future will be the fruit of 
human deliberation, judgment, and choice; it is not subject to fixed 
laws of history and forces of social determinism. As the Marxists 
learned the hard way, the reality of human freedom is the permanent 
foiler of “inevitability” theses. Same-sex marriage and the assaults on 
liberty and equality that follow in its wake are “inevitable” only if 
defenders of marriage make their adversaries’ prophecies self-fulfilling
 ones, by buying into them.
