Christopher, you just threw a 50 point double bullseye!
Here is my reply to a thread that goes back a couple of years ago on a subject similar to this:
Remember when we all forced to take American History back during our high school years? What was the reason that the first American settlers left England in the first place? Does something to do with "freedom of religion" ring a bell? But why did they want religious freedom in the first place? In the early 1500's, England broke away from the Catholic Church, whereupon King Henry VIII (i am i am) established the Church of England and named himself the head of the church, and according to English law, all citizens had to belong to the Anglician Church and contribute to it's support regardless of their own beliefs. Of course plenty of people objected to having to support something they did not believe in, and after being persecuted for their beliefs, that prompted people to seek out freedom in the "new world". Years later when the constitution was being drafted, the founding fathers chose to create a democracy, not a theocracy, which is why the first amendment reads:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.
I'm no constitutional scholar, but that seems pretty self-explanatory to me. The government will not make any law favoring one religion over any other, nor will the government prohibit anyone from exercising their free will to believe (or not) in whatever way they see fit.
Of course the next morning I got accused of not having a "basic knowledge about everyday life in this country", and If I believe that this nation was not founded upon Christian principles, that is my right and I have the freedom to believe so. However, that does not change history.
