The 'when in Rome' argument is at best insipid. You are asking people to compromise their convictions simply to prevent others feelings from being hurt due to the discovery that not everyone thinks like them. Sorry, but that's a lesson everyone needs to learn sooner or later, and the sooner, the better. It is true that there are court decisions on the books saying no student can be forced to recite the pledge. It is equally true that there are many school administrators who remain ignorant of these decisions, or who intentionally choose to ignore them.(Quite a lesson in citizenship being taught by example.) Here's just one example: http://www.huffingtonpost.com/2012/06/08/pled... Note the part about the student having been 'repeatedly suspended' for refusing to recite the pledge.<quoted text>
The recitation of the pledge of allegiance is voluntary so no one is required to recite it. Another interesting quote is, "When in Rome do as the Romans do". Most people tend to conform more or less to the moral system in which they are born and as the French historian Alexis de Tocqueville stated the United States is probably the most Christian nation he observed and the main reason for its greatness.
So, you get your morals from the bible, do you? Really? When's the last time you killed a gay person or an adulterer? What, you've never done so? Why not? The bible says god commands you to do this. Ever go shopping on a Sunday? The bible says that is wrong, and deserving of the death penalty. Do you own any slaves? Why not? The bible says it is A-OK with god, so long as you don't beat them so badly they take more than a couple of days to recover and you don't break their teeth or hurt their eyes. Did you kill any of your children when they sass you back? Why not? The bible says god ordered you to do so. Do you condone genocide or the killing of innocent civilians during war? Why not? The bible god heartily endorses this, and he is even displeased when his forces leave some of the womenfolk of their enemies alive.As far as a moral foundation for atheism, Vox Day pointed out, "Still, even the most admirable of atheists is nothing more than a moral parasite, living his life based on borrowed ethics. This is why, when pressed, the atheist will often attempt to hide his lack of conviction in his own beliefs behind some poorly formulated utilitarianism, or argue that he acts out of altruistic self-interest. But this is only post-facto rationalization, not reason or rational behavior."
The fact is, you, like all civilized people, reject these biblical commands. In doing so, you apply a moral sense that does not come from the bible, to help you filter which bits of the bible you will follow, and which you will claim are no longer in force, leaving aside the fact that if your god were perfect, as you claim, he would be incapable of error, and thus would not have proclaimed these things moral. We both derive our morals from somewhere other than the bible. Atheists are just more about it.
