Is this the norm in elementary schools now or should I seriously consider moving?

That's just your area. While I understand giving Hispanics respect and I'm all about equality for everyone, that's a little overboard, in my opinion. I'm uming you're in America... why would the pledge of allegiance be offensive? o_O That's a new one on me. If I were in your shoes, I would consider moving. Do some research on different schools in different area's where you would be able to afford living, and go from there.
