I'm an anomaly among right wing conservatives in that I hold no delusions about invisible bullies who live in the sky and I don't take marching orders from ancient books of ridiculous fairy tales.
Don't these idiots know the Declaration of Independence is not a legal document and has no enforcement value? Even if it did, it only mentions "Natures God" in deist abstract. No mention of Jesus is found. No words such as "God", "Lord" "Jesus" "Christ" (or "Democracy" as a matter of fact) are found in the supreme law of our land, The United States Constitution.
What is contained is the First Amendment which mentions "no law respecting an establishment of religion" as well as Article 6, paragraph 3 which states "no religious test shall ever be required as a qualification to any office or public trust under the United States."
I always thought George Carlin was a jerk, but I agreed when he said "Keep your religion to yourself!"
