We have often, on economic and foreign policy matters, found common cause with the people who call themselves conservatives. But on most social issues, they are on opposite sides of the issue from my own feelings. I am sure this will be equally true with regard to the new California Supreme Court decision.
I have never understood why conservatives, who believe that in the economic sphere the government should be minimally involved, letting the market mechanisms do their thing, suddenly, when the issue is social, take the position that the government should take a stand and ram that position down the throats of the people. If two gay people get married, who does it hurt? It certainly doesn't affect a straight person's ability to marry whomever he or she wants.
Some people have said that there is no equality issue here, that gay people are trying to win special privileges that straight people do not have -- I suppose, because straight and gay people alike have the right to take an opposite-sex spouse. Well, Anatole France is quoted as saying: “The law, in its majestic equality, forbids rich and poor alike to sleep under bridges, beg in the streets or steal bread.” Obviously, just in the same way as rich have no particular reason to "sleep under bridges, beg in the streets or steal bread," gay people have no particular wish to take an opposite-sex spouse.
Some people have claimed that, by requiring the state to recognize gay marriage, the rights of clergymen who do not want to officiate over such marriages are somehow interfered with. Well, to my knowledge, no Catholic priest has ever been forced to officiate at the marriage of a divorced Catholic, and no Jewish rabbi has ever been forced to officiate at an interfaith marriage. If clergymen are now allowed to refuse to marry people whom their own religion forbids to get married, they certainly will continue to be allewed to do so. We are talking about state recognition of marriages, and we live in a country with Church/State separation.
Another point is that, in a referendum, the California citizenry voted to ban gay marriage. I am sure that in any Southern state (and possibly some Northern ones) the citizenry, if provided with a referendum vote on the subject prior to 1954, would have approved of segregation. But we do not allow the majority to take away the minority's rights. That is a fundamental principle of the American democratic system.
So I cheer the California decision.
