Do you think their is a moral basis for parts of the Constitution? Does self defense have a moral component? Life? Liberty? Property?
Caught that later, forgivable misteak! ;)

Yes, certainly moral reasons for the Declaration of Independence and the Constitution were advanced at the start of this nation. The Framers had to get people to make the leap from governance by a King who was the representative of God, to the idea that certain rights were God-given, and not awardable by a King. But just because a purely religion-based strategy had to be employed 200 years ago, doesn't mean that we cannot come up with other reasons for self-governance now, that rely on the dignity of human beings, without reference to traditional Western religious concepts.
Believe me, when we're dealing with people who are adamently in favor of gay marriage, we're talking to people who believe that the pursuit of happiness that they find in the Constitution applies to homosexual relations. At least that's what I read in the Lawrence majority decision.
