Nah. We should not give up or give in. I just believe in this matter, that the citing of the Our Pledge of Allegiance, there is no issue. No giving in, imo, is being done. There has to be written rules. There has to be unwritten rules also. The matter of which we judge these is very delicate. And you are right. You give an inch and they take a mile. That goes with everything. Also, we have to remember, if I remember correctly, all of these men who had a hand in getting all of our constitutions and such written, they were not all "Christians". Most, however, did believe in some sort of creator. How they all came together on this is amazing in itself. Apparently, at one time or another, Thomas Jefferson, did not believe in Jesus Christ being the son of God. Below is he statement about it. So, above, because these people do not believe exactly how we do, this must, no can not, be the same God.
""And 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. But we may hope that the dawn of reason and freedom of thought in these United States will do away with all this artificial scaffolding, and restore to us the primitive and genuine doctrines of this the most venerated reformer of human errors." -- Jefferson's letter to John Adams, April 11 1823
