Further nonsense.
It's not in question that some of the founding fathers were Christian. Not all of them were however, and some who were were not nearly as devout as you'd think.
The reality is that many of them had their doubts, and the Constitution and first ammendment were written accordingly. This whole notion that we are a "Christian Nation" didn't really come into being until the Second and Third "Great Awakenings" occured, long after the founding fathers were gone.
Thomas Jeffson wrote in 1823:
"The day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin, will be classed with the fable of the generation of Minerva in the brain of Jupiter."
Thomas Jefferson in 1779:
". . . no man shall be compelled to frequent or support any religious worship, place, or ministry whatsoever, nor shall be enforced, restrained, molested, or burthened in his body or goods, nor shall otherwise suffer, on account of his religious opinions or belief; but that all men shall be free to profess, and by argument to maintain, their opinions in matters of religion, and that the same shall in no wise diminish, enlarge, or affect their civil capacities."
Thomas Jefferson in 1813:
"History, I believe, furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance, of which their political as well as religious leaders will always avail themselves for their own purpose."
Thomas Paine in 1794:
"I do not believe in the creed professed by the Jewish Church, by the Roman Church, by the Greek Church, by the Turkish Church, by the Protestant Church, nor by any church that I know of. My own mind is my own church."
Also by Paine in 1794:
"All national institutions of churches, whether Jewish, Christian or Turkish, appear to me no other than human inventions, set up to terrify and enslave mankind, and monopolize power and profit."
Again:
"Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind."
Benjamin Franklin in 1790:
"As to Jesus of Nazareth, my opinion of whom you particularly desire, I think the system of morals and his religion, as he left them to us, the best the world ever saw or is likely to see, but I apprehend it has received various corrupting changes, and I have, with most of the present dissenters in England, some doubts as to his divinity, though it is a question I do not dogmatize upon, having never studied it, and think it needless to busy myself with it now, when I expect soon an opportunity of knowing the truth with less trouble. I see no harm, however, in its being believed, if that belief has the good consequences, as probably it has, of making his doctrines more respected and observed, especially as I do not perceive that the Supreme takes it amiss, by distinguishing the unbelievers in his government of the world with any peculiar marks of his displeasure."
Sure you can find other quotes from other sources that show some support, but the reality is that these were not deeply religious men. Many were considered Deist - the equivalent of what we in modern times call an Agnostic.
Careful with all those facts though. Might hurt your head.
Now, in regards to:
Now, explain to me how flying a Christian flag in an obscure corner of ANY park would be forcing religion on anybody?? Ridiculous.
It's not. However, lets look at the First Ammendment:
"Congress shall make no law respecting an establishment of religion,
or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
subdjoe basically already makes this point. It doesn't just say it cannot force a religion on people. It says that it can make no laws "prohibiting the free exercise therof". What that means is that if you allow ANY religion a particular boon, you must allow it to ALL of them. If you want to allow a Christian flag you would, at a minimum, have to allow any relgious group to fly their flags in the location. To do otherwise would be treating them differently. You can't make an exception for one.
Any time when you involve government laws, priviliges, acts, property, or anything else dealing with the government, if you want the Christianity treated any differently than any other religion, you're going to run afoul of the 1st ammendment. Get over it.
