You are good at cutting and pasting everyones opinions. Could you please cut and paste the part of the Constitution about separation of church and state for us?
Try reading, perhaps very slowly, the First Amendment to the Bill of Rights. It is the reason religion has flourished in the U.S. while the state churches of Europe have died out. Jefferson and other founders intended that religion, specifically the Church, not become an arm of the State --- nor in turn coerce or control the State. Jefferson and Adams looked for the day when the states, especially those of New England, would follow the lead of the South and leave off state sanctioned churches - whether one or several denominations.
