This article is ridiculous. America was founded primarily by Christians, based upon Biblical principles (as well as borrowing other elements from Anglo Saxon law, the Romans, etc.). That said, the Biblical principles used were also in large part contained in the Old Testament, thus “Judeo-Christian values.” I don’t see the conflict.
I should have added that I get the comment about mentioning “Merry Christmas” and “Judeo-Christian values” together, but come on, we all know what he meant.
Christianity began as a Jewish sect and became a global religion on a foundation of Jewish history and teachings. Without Judaism, there is no Christianity.
