Dear Stupid CON...
Jesus was a liberal. In fact, he was a radical, pacifist, peace & love, long-haired HIPPIE liberal. A Jewish one too!
Our Founding Fathers were also liberals. Radical, revolutionary, anti-government, anti-religion liberals. They believed all men (ok, all white men) are created equal and should be treated equally under the law. Because the Brits treated some men as gods on earth and other white men as slaves - look at the British class system, or how they treated the Scots, Irish, etc. - people practically identical to them, not to mention the vast majority of Englishmen were treated almost as bad.
Finally, the United States was NOT founded on "Christianity principles" - the Founding Fathers said so themselves! See Treaty of Tripoli, which contains these words: "... the Government of the United States of America is not, in any sense, founded on the Christian religion..." and was ratified by the U.S. Senate and signed by the U.S. President. It doesn't get any clearer than that!
