Not even the Founding Fathers stuck by the so called " principles ", that so many here claim they had. That may be, but at least they acknowledged and articulated the principle that our rights come from God. Without that principle, our society would never have come to be.
And some of them, dear, thought that slavery was okay / a necessary evil / or
PRAGMATICALLY gave in on that subject. The Bible doesn't find fault with slavery. No, don't even attempt to argue that it does. That the Chosen people were in bondage, was turned around, when they were slaves in Egypt; GOD didn't send another Moses, when they were again enslaved. Heck, HE even allows the Hebrews to have slaves of their own.
Slipping into refferences about GOD and what's in the Bible, isn't going to shore up your " principles " arguement. It's also the last ditch of scoundrels, dear. :-)
