We're not a Christian nation, and historically we have not acted like it.
That has to be one of the most il-informed comments I have ever read. Try reading what our founders wrote themselves about their reasons for the way they set up this country and about their fears if we lost our Christianity and the effect they foresaw it would have on our freedoms. Historically we have acted like a Christian nation over and over and over again, but now that we are loosing our Christian roots things are changing.
