California's Supreme Court today struck down state law's same-sex marriage ban, finding the state's constitution "properly must be interpreted to guarantee this basic civil right to all Californians, whether gay or heterosexual, and to same-sex couples as well as to opposite-sex couples."
There might be no better articulation of why this makes sense than this bit from San Diego mayor Jerry Sanders. Sanders is a conservative who had vowed to veto a city council resolution allowing gay marriage. He changed his mind and very poignantly and clearly explains why. I, for one, can think of nothing more to add.
