Geez. I see this argument so much that I just have standard point form rebuttals now.
1. "Treaty of Tripoli", Article 11, Wikipedia it, nuff said.
2. "Most of your founders were deists, atheists, or laymen in general with little use for religion who believed firmly that religion having a hand in what went on in politics was not the way to go about things." The constitution has a whole section devoted to this. Have you read the thing? Any references to "God" in the constitution are to say he has NO PLACE IN POLITICS. And since you've obviously never read it, I don't trust your count.
2 sub a. Your founders, in writing the constitution, knew just how screwed up religion tends to make countries where it has undue influence. So, they took precautions against it. They may have been hedonists and sinners to a man, but they never did anything as bad, in the name of their deism, agnosticism, or atheism, that was one tenth as bad as ninety percent of the horrible things that are done in the name of "God", and all the purported charity of god-fearing men and women (a phrase which I hate), does not take one chip out of your karmic load.
2 sub a point one: Whenever you falsely assert the belief in god as part of the forming of the US constitution, political ethic, or even as a notion which was in the heads of the revolutionaries who separated America from British rule, an irony meter explodes. THE SEPARATION AND REBELLION WERE ABOUT DIVORCING THE NATION FROM RELIGIOUS TYRANNY, at least a little bit! Religious freedom, or, the freedom FROM religion, were some of the most important issues.
2 sub a point two: On the other hand, every time you assert something crazy, untrue, dramatic, and easily impeachable, you make the kind of people who think like you look a little more ridiculous in the eyes of everyone who's sane.
2 sub b: Also, whenever you assert things like this, your God sends another hooker into Atheist Heaven, in accordance with a bet he made with Socrates, and sends over a few more kilos of "the good stuff", in accordance with a stoned bet made with Darwin. So, you know, all you're doing is putting sanctified hookers around Socrates' schizophrenic johnson, and sanctified spliffs in Darwin's hands. Is that what you want?
2 sub b point one: Please, don't do stupid things. Won't you think of Darwin's brain cells?
