I agree with you. The problem is how the government works in California. Representative government is a joke out there. All anyone has to do is get a certain number a people to sign a petition and then their issue become a proposition on a ballot. So the people are directly involved in what becomes law in their state. Sounds nice enough in theory, but what you get is things like Prop 8.
Despite the ethics of the proposition, which really are horrendous, Prop 8 is technically legal. It went through the proper channels to become a law and the prosecution in the case did have much of a legal case against it. Which is why the Supreme Court upheld it. It boils down to how people personally feel about it, not what is legal.
At least they achieved a small victory in that all marriages performed after the initial lift of the ban are still legal. However, the fight is not over. The good news is, since California government system is screwed up, there more than likely be a proposition on the ballot soon to legalize gay marriage.
