Tony Blankley has a great column, “Secession,” you need to read:  http://www.townhall.com/columnists/tonyblankley/tb20041110.shtml

Quoting from his column:

This dominant sentiment of the Democratic Party elite — that scores of millions of Americans are categorically unacceptable as fellow countrymen — is evidence of a cancer in the soul of that party. These Democrats, quite expressly, are asserting that “christers,” people who believe in the teachings of Jesus as described in the inerrant words of the Bible, are un-American, almost subhuman. Some of these Democrats would rather secede than stay in the same country with such people. If they were in the majority with no need to secede, what would they do? Their bigoted and absolutist view of religious people is at least a second cousin to the Nazi view of the Jews.
