Considering the fact that the definitive version of a "God" is absolutely reflected upon an individual's perspective of their own life and their surroundings or by what they have encountered/experienced, why should anyone have a problem with it? Throwing an occasional "God" into the verbal mix shouldn't hurt anything! Regardless, God means something to everyone, whether they are an atheist or not. I mean really, to some, the term simply means existence within the universe and the ability to view everything as a whole as we are all a part of God, while others think solely of their self and see the term God as bogus hooey made up by others so they could control their life, and many think of some divine being that is in charge of the force behind all things while some think that God merely equals energy, and there are those that simply don't give a rat's ass either way.
However you look at it, we are all under the great chaos, grand confusion via the gargantuan, garish God concept, whether we admit it or not because, uh, duh, nobody really knows exactly what in the hell is going on here... My Gawd! What is it with the Godphobic freaks? How can you have a problem with a 'term' that you personally define? Each individual can conclude what they think on this matter and it is just a word, so therefore, what difference does it make if it's in the Pledge of Allegiance or not? What if you have a problem with the word 'justice'? Should that be took out, as well?
