Then why not just answer the question do you agree with the zotted troll (OldSpice) or not? Do you think that many or most of the Founding Fathers were atheists? Do you think that America was founded on the principles of atheism?
Leaving the Episcopalianism of George Washington and James Madison aside for a moment, it was widely thought by Hamilton and the Federalists that Jefferson was a flake. Whether the main problems were sexual, who knows. The "wall of separation" comment in a private letter on disputes between Baptists and Anglicans in Virginia is a private opinion, is not in the U.S. Constitution, and has no force of law, however many secular humanist crackpots invoke this as part of their anti-Christian theology.
"In 1812, President Madison signed a federal bill which economically aided the Bible Society of Philadelphia in its goal of the mass distribution of the Bible."
If he were a secular humanist opposed to Christianity, this was a funny way to show it.
