There are three reasons why Professor Berg's argument does not quite come full circle.
First, the suggestion that marriage rights have to be balanced equally with religious rights, in general, assumes the value judgment that those rights are of equal weight. In this way, Professor Berg, like many colleagues influenced by the classical liberal (lowercase "l") foundations of our constitutional and legal philosophy, suggests that individuated rights are the central values in the Constitution, leaving little guidance on how to mediate between those rights. I do not believe that to be the case, but even if I concede the philosophical point, American society has already proved him wrong. As I have argued here, the pervasive existence of public accommodations laws that ban this type of discrimination manifests the public's judgment that cooperation and equality are more important to us than radically individuated religious observance.
Second, even if you do not believe that our society has made that value judgment — it is indeed up for debate — there is a qualitative difference between a right of inclusion and a right of exclusion. In re Marriage Cases and the Massachusetts same-sex marriage decision, Goodridge v. Department of Public Health, included the gay community in the institution of marriage; religious exceptions to such inclusion excludes the gay community from public accommodations. Normally, exceptions to default rules require special justification. They are rarely of equal value to the basic right in question. And, they are meant to be narrow. Professor Berg would extend the right to exclude the gay community from public accommodations to anyone who follows a conservative religious ideology, significantly expanding the orbit of discrimination.
Third, it makes no sense that Prop 8 — the ban on same-sex marriage in California — was a rational public response to a California Supreme Court decision (In re Marriage Cases) that inadequately protected religious liberty. Professor Berg cites from an amicus brief from the Becket Fund for Religious Liberty argued in Perry: "Since the California Supreme Court left Californians with an all-or-nothing choice between same-sex marriage and full protection for the rights of conscience, Proposition 8 was an entirely rational response to the threat to religious liberty." No, it wasn't. A rational response would have been an initiative (assuming we needed an initiative) that codified religious exemptions to default marriage recognition. If the problem was the lack of religious protection, then the solution to the problem was to add religious protections, not overturn the entire law. Prop 8 was an overreaction, and thus an irrational reaction.
Professor Berg is not wrong about the relative institutional abilities of courts and legislatures: it is certainly harder for courts to adequately craft rules that balance competing interests. But, that does not mean that Prop 8's discriminatory ban on the entire institution of same-sex marriage was a rational response to a much more narrow problem.
