"appears to be pretty religious" ....no kidding. Pretty religious verging on crackpottery .
A perspective that starts out with "The founders of America (the Puritans).." and contains such nonsense as "The U.S. Constitution is just a piece of paper with signatures on it.", is going to be as much balance as no balance at all.
That style of factually absurd incorrect and historically inaccurate commentary is all religious argument ever has.
American Founding and Law came about despite religion not because of it. The Constitution is the most important legal document there is and of course, Virginia had already been founded in 1607, 23 years before the Puritans ever thought of following suit in 1630.
