Logic problem: The founding principles of the U.S. and Christianity.

[Ziploc Surprise]

I have a small logic problem. Many Christians promote the belief that the U.S. was founded as a Christian nation. As some of their evidence they say that the founding fathers were Christians, and that the country was founded on Christian principles (for more see the video link).

Here's a link to what these people believe, it's pretty nauseating. http://www.youtube.com/watch?v=yArlBOPTeFg

Here's my problem: Aren't ideas like freedom of religion and the separation of church and state naturally opposed to what seems to naturally become the Christian agenda (that is to dominate, oppress, and take over)? If the founding father's really were Christians bent on making this a Christian country why would they want freedom of religion and a separation of church and state? Wouldn't that interfere with their agenda? Wouldn't it lead to the most powerful church taking over? If we in the U.S. were to go back to our Christian roots so to speak won't that involve trashing freedom of religion and the idea of separation of church and state?

Oh, and by the way, if someone wants to bring up the worn out argument "That the separation of church and state does not exist in the constitution" please read this first so we can get this bit out of the way. http://atheism.about.com/b/2010/01/17/no...-state.htm This link also explains that, while the U.S. has a history of practices that crossed the boundary of church and state many times, it doesn't negate the founding father's original intent so I think I can say that I've killed two birds with one stone so to speak.
