Fifty Questions That Christians Can't Answer

[Minimalist]

I think the US legislating for religious freedom and non involvement in government is actually completely in line with Christian thinking BTW.

You are confusing morality with the great fear of the Founding Fathers, Frodo. This quote from Jefferson is what they were striving to avoid.

Millions of innocent men, women, and children, since the introduction of Christianity, have been burnt, tortured, fined, and imprisoned; yet we have not advanced one inch toward uniformity. What has been the effect of coercion? To make one-half the world fools and the other half hypocrites. To support roguery and error all over the earth.
-- Thomas Jefferson, Notes on the State of Virginia, 1781-82

"Religious freedom and non-involvement" by government was seen as a CURE to hundreds of years of Xtian bloodletting and barbarism in Europe. The entire Enlightenment was a repudiation of xtian tyranny.
