Things in these disciplines are questioned and contradicted all the time. Which is why they’re not indoctrination.
What is questioned about English? The rules are the rules. What about Math? How do you question Math? History? You can put a different spin on it I suppose, but for the most part, history is immutable. Geography can't be questioned. A river is where a river is, and it's as long as it's been measured as being. Science? Most of science can't be questioned. There are theories which some suggest might be mutable, but that's a small percentage of the whole.
