If this were true, there would have been no Scopes Monkey Trial. Neither is a school free to teach you that 2+2=5 or that pi is 3.2, even in Indiana. How's that for 1st amendment?
You're really just flailing about hoping something will land. It's amusing to watch, but that's all.
If you'd like to get as good as you're giving, how about you tell us what country you're from, so we can provide an opinion about choice episodes in its history in return? Fair is fair, no?
Second, Americans, I think, would be really uncomfortable with the idea of a government entity controlling how people are supposed to speak and write. That lives too close to controlling what we say and think. Not that such an entity necessarily leads to 1984-style propaganda and thought-control, but we take First Amendment concerns very seriously here.
Lastly, if you attend a specific school, you are subscribing to the instruction of that curriculum and those teachers. To have all students everywhere subscribe to the same authority of what they should know and how they should think... that can be pretty scary for an American.
