Schooling in America has little to do with education, and much to do with indoctrination.
Pretty much the only thing I learned was the pledge of allegiance - over which I repeatedly got suspended, as I refused to recite it along with the rest of the class, every morning.
Everything else they "taught" was years behind what I'd been learning elsewhere, and none of it was teaching - it was all just OBEY. I used to kick like a mule whenever they tried to teach us something factually incorrect by rote - and got in trouble for it.
THERE ARE FOUR LIGHTS!
