Moral Relativism

This is a short thought I had last night. Moral relativism, politically, boils down to the majority. Short of regressing to tribalism, this means that there will always be a minority (or more) in disagreement over legislation. The only thing stopping an infinite loop is how the Supreme Court system works, for better or worse. So long as moral relativism is used for "freedom," its supporters will always have the usual crowd of "bigots," "haters," and so on to contend with. Perhaps relativists would be best served reviewing why they want things a certain way. In my interactions in life, it has always boiled down to personal want. Regardless if this is the majority position or not, I wonder when humankind will realize that they've been acting out of physical want their entire existence, ignoring the soul?
