Then you disagree wrongly. The history of the courts shows them upholding rules AGAINST minorities probably as much or more so then "stepping in" to protect.
Not as much anymore. In most cases in say, the last 3 generations or so....if protecting the rights of minorities is on deck, they abstain from ruling or rule in favor of the minority rights. Ruling against them is no where near as common.
And since the modern judiciary is what we'll be dealing with in a gay marriage ruling, I think that the protection of minority rights from the majority is a distinct, perhaps even probable outcome. It all depends on Kennedy. Who has a thing for protecting gays from discrimination from State laws and for protecting States rights. So it could go either way....though I think Kennedy will ultimately side with gays. Especially since the idea seems to be taking such root across the nation.
The "rights" in our Constitution were AMENDMENTS passed by THE MAJORITY.
True enough. But the interpretation of the constitution is largely left to the courts. And of course, the bill of rights simply articulated rights that the founders insisted we already had. It didn't create rights. It codified them. And as the 9th amendment makes clear there are far more rights than those listed in the Bill of Rights.
The courts are the body most commonly used in articulating these 'unemumerated' rights. Like...the right to privacy. Or the right to self defense with a fire arm.
