Are we a Christian nation?

To myself, it is clear this nation was founded on Judeo-Christian principles. The Idea that this country declared it's independence from England based on God-given rights, which no government of man has a right to deny, came from anywhere but the respective faiths of those who wrote it just doesn't make sense to me. Now certainly, as it is stated in the Constitution, this nation does not discriminate against any faith, in fact, our country welcomes people of all faiths who wish to seek asylum in this country from outside oppression. But for our President to say we are "not a christian nation", to me, is yet another example of a man who has no respect for the office he holds, or for the people he represents. Maybe he should pull a dollar bill out of his pocket and read the quote, "in God we trust." Maybe he should wonder who he is referring to in the pledge of alliegence when he states, "...one nation, under God...". Mark Levin's chapter "On Faith and the Founding" in Liberty and Tyranny explains The framers were not all of the same faith. The Puritans came from New England, Quakers from Pennsylvania, Catholics from Maryland, and so on. He goes on to point out they were all seeking freedom from religious persecution. There is no arguing they were Christian men. There is no arguing it was the Judeo-Christian values of the Framers which provided the point of view in forming the Declaration of Indepence, and our Constitution. John Adams said, "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
The modern liberal has no use for God in their vision of Utopia. God gets in the way of the liberal agenda. You see, God has given you rights, what the declaration refers to as "Natural Law", rights upon which NO government may impede. As this government moves ever closer to despotism, expect more attempts from Obama to remove God from the fabric of American Civil Society. For if God is not in the equation why then, I suppose our God-given rights don't exist. Mark Levin writes, "The Statist (liberal) cannot abide the existence of Natural Law and man's discovery of "unalienable rights" bestowed on all individuals by "their Creator".....The Statist believes rights are not a condition of man's existence but only exist to the extent the Statist ratifies them."
