I glad you are more moderate than your original post suggested.
Now, I will intelligently disagree with your post in a couple of areas.
It is not correct to say this country was founded on "Christian principals".
The main principals of Christianity, at least as outlined in the Bible, are absent from our founding documents or our laws. I would include loving your neighbor, helping the poor, peacemaking, non-judging, turning the other cheek, honoring the king... These principals are all prominantly featured in the Bible.
If you have any doubt about the Christianity of the founding fathers, read Romans 13
The Apostle Paul wrote:
Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves.
It is clear that true Christians did not take part in the Revolution that started our Nation. There is no Biblical example of a rebellion that was supported by God-- even though the early Christians lived under a government that was far more unjust than the British Monarchy.
Likewise the main principles the United States was founded on are missing from the Bible (or previous Christian teachings). At the time, most Christians in the world were Monarchists as Christianity was used to defend Monarchy for a long time.
There is no mention of Democracy in the Bible. The closest you come is in Numbers 16. It was strongly condemned by Moses.
There is history of freedom of speech in Christianity, no separation of powers, no guarantees of privacy.
The people who founded our Nation appealed to Reason as a counter to religion. I say we do well to keep it this way.
