All teaching involves coercion. It's indoctrination into the mode of thinking of the teacher. If it's a Christian or a Muslim teacher, they'll teach them to be a Christian or a Muslim. Most teachers coming out of college are communists, whether they're open about it or not. They're often not even aware of the bad ideas drilled into their head that they take for granted. No matter what the curriculum is, why would you trust your children to a low IQ brainwashed commie?
