Even if childhood coercion has virtually no effect, it would not change what it is right or wrong to do to people. And it is not right to do things to people that will impair the growth of knowledge.
How you think people learn informs all your interactions with your children. If you view learning as a creative act in a critical-rational process, you will value highly the idea of consent in decision-making. If you believe people learn through divine revelation or by having knowledge poured into them, that will inform your interactions in a different way from if you think that they learn through conjectures and refutations: you may well think coercion necessary.
