I'd like us to be careful about phrasing with respect to what "people" want. People had their will thwarted not only by this California Supreme Court opinion. Other people had their will thwarted by the gay marriage ban. Say "the majority" if that's what you mean. I'm straight, but even I am a little bit unnerved when language seems to imply that same sex couples are not people, or they do not have a will that can be thwarted.
The First Amendment not only contains the Freedom of Religion clause and the Freedom of Association clause, it contains the Establishment clause. The government can't make normative laws in this area of religious thought, period.
