Since the cases involving same-sex civil marriage have finally reached the California Supreme Court, it may be helpful to repeat comments on this from an earlier post:
Allowing the state to dictate the terms and conditions of that institution as blithely as American Christians do is a mistake. We’ve already seen that many of those terms and conditions have been changed at law. The opinions of both the Governor and Jr. Brown confirm the obvious: with marriage, what the state gives, the state can take away. (The phrase "rational legislative purpose" is absurd; legislatures do all kind of things for all kinds of reasons, rational and irrational.) The "rights" of civil marriage are in reality very ephemeral, which makes one wonder why some are fighting so hard to obtain them.
