I presume you're in America, right?
The school district thinks they own you, and they're pushing you around. And you're not gonna do a thing about it, nobody ever fights for themselves.
It's quite a shame that even in America, kids are treated more like Pets than people. They expect you to come when you're called, and when you do they think your parents have succeeded, but you could say that about anyone and they could turn out to be a serial killer.
Also they force you to do the pledge of allegiance, basically they're forcing you to be a patriot. That's how much power they think they have.
