When a judge goes beyond [his proper function] and reads entirely new values into the Constitution, values the framers and ratifiers did not put there, he deprives the people of their liberty. That liberty, which the Constitution clearly envisions, is the liberty of the people to set their own social agenda through the process of democracy.
In a constitutional democracy the moral content of law must be given by the morality of the framer or legislator, never by the morality of the judge.
Being 'at the mercy of legislative majorities' is merely another way of describing the basic American plan: representative democracy.
