The Prop 8 decision sucks, but it was NOT about denying equal marriage rights. It was about whether or not the state constitution could legally be modified by a simple majority.* That analysis is completely independent of how the court may feel about the issue being modified. Reframing it as "OMG teh CA Supremes hate teh gays!!1!" just makes you look stupid.
So now, California: change it back! And don't let the Mormons make up your minds for you this time!
*Yes, it's stupid for a government to work this way. But this is the same state that voted in the Governator with a plurality in a 20-way election. Sense, it would seem, did not apply when they wrote that Constitution.
