First of all, I'm proud of you for giving space for kids who do not want to participate, seriously good for you! However, am I fair to guess that few, if any, opt out? That said, we aren't all that unique; it's simply most adults aren't faced with having to give the pledge of allegiance. I recall that movie Runaway Jury where the mole in jury convinces everyone to say the pledge, and how everyone is like wtf is this. As children we don't think twice about how weird it is. But it is weird. Maybe teachers are so institutionalized they don't either, but it's super odd for a free society to ask children to prove their patriotism by oath, each day before beginning their education. Yes, it's what makes dystopian fiction.
