As an American, I can honestly say I don't think it matters. I don't believe that any compelled or tricked oath is binding, much like a "broken seal" or click through EULA.
It's not legally binding, that is certainly true. All the same, I would maintain that it does more harm than good to require citizens to pledge allegiance in a way that forces them to submit themselves to something they don't even believe exists. "One nation under god" implies that we are under the dominion of a deity, and that concept completely violates not only my understanding of our nation's philosophy but also of my own personal belief system. Inasmuch as freedom of religion and freedom of speech are considered essential to life, liberty, and the pursuit of happiness, I would hold that requiring citizens to recite the Pledge of Allegiance violates the principles upon which this nation is founded. Regardless of the fact that the pledge is not legally binding, I still do not find it so trivial as to dismiss enforced recitation of it as something that "doesn't matter."
I think the indoctrination of our more sheep-like young citizens is thoroughly accomplished during the other 15 hours and 59 minutes of the day. I think that it might provide a useful lesson in the ways of the world to our more cynical students, and a demonstration in etiquette to our more aware ones. But again, that's readily done elsewhere.
Are you saying that recitation of the Pledge should be required because it teaches students that liberty is an illusion? Furthermore, are you defining etiquette as the art of going along with the crowd and/or authority figures in spite of having to violate the most basic elements of your belief system to do so? Wow, that's pretty cynical. If that's how you see things, then you must think that the U.S. Constitution is nothing but a worthless old rag either. Perhaps you think we should just abolish the Bill of Rights altogether and accept the ways of the world with no delusions of individual freedom.
