Argument: Gay marriage discrimination lacks compelling state interest
"Let them wed." Economist. January 4th, 1996: "To this principle of social policy, add a principle of government. Barring a compelling reason, governments should not discriminate between classes of citizens. [...] the state should presume against discriminating—especially when handing out something as important as a marriage licence. Thus the question becomes: is there a compelling reason to bar homosexuals from marriage? [...] One objection is simply that both would-be spouses are of the same sex. That is no answer; it merely repeats the question. Perhaps, then, once homosexuals can marry, marital anarchy will follow? That might be true if homosexual unions were arbitrary configurations, mere parodies of “real” marriage. But the truth is that countless homosexual couples, especially lesbian ones, have shown that they are as capable of fidelity, responsibility and devotion as are heterosexual couples—and this despite having to keep their unions secret, at least until recently. Would gay marriage weaken the standard variety? There is little reason to think so. Indeed, the opposite seems at least as likely: permitting gay marriage could reaffirm society's hope that people of all kinds settle down into stable unions."
Scott Bidstrup. "Gay Marriage: The Arguments and the Motives": "1. Marriage is an institution between one man and one woman. Well, that's the most often heard argument, one even codified in a recently passed U.S. federal law. Yet it is easily the weakest. Who says who marriage is to be defined by? The married? The marriable? Isn't that kind of like allowing a banker to decide who is going to own the money in stored in his vaults? It seems to me that if the straight community cannot show a compelling reason to deny the institution of marriage to gay people, it shouldn't be denied. And such simple, nebulous declarations are hardly a compelling reason. They're really more like an expression of prejudce than any kind of a real argument. The concept of not denying people their rights unless you can show a compelling reason to do so is the very basis of the American ideal of human rights."
Robert Levy, Chairman of Cato Institute. "The moral and constitutional case for a right to gay marriage." New York Daily News. January 7th, 2010: "To pass constitutional muster, racial discrimination had to survive "strict scrutiny" by the courts. Government had to demonstrate a compelling need for its regulations, show they would be effective and narrowly craft the rules so they didn't sweep more broadly than necessary. That same regime should apply when government discriminates based on gender preference.
No compelling reason has been proffered for sanctioning heterosexual but not homosexual marriages. Nor is a ban on gay marriage a close fit for attaining the goals cited by proponents of such bans. If the goal, for example, is to strengthen the institution of marriage, a more effective step might be to bar no-fault divorce and premarital cohabitation. If the goal is to ensure procreation, then infertile and aged couples should be precluded from marriage."
