The United States is not a Christian Nation?

I believe you've confused the US with the Holy Roman Empire; it's okay, I do the same exact thing ALL the time. I'm sure you've read the Constitution and that little piece of paper added to it called the Bill of Rights. I mean, how could you make an intelligent argument to cling to your guns if you hadn't? Also, ha. Your militia better stand a chance against predator missiles if you want to make sure the 3rd Amendment isn't a load of garbage. But anyway, yeah, Constitution.
