Surely children are not born knowing right and wrong?

Children are not born knowing right and wrong arises out of the paternalist view of children, which mistakenly holds that children learn moral knowledge through coercion, and that no one would have any interest in improving their moral knowledge unless forced to do so. But actually, coercion impedes and impairs learning, including of moral knowledge, and the vast majority of people including children are trying to do the right thing and trying to improve, including morally, and no one has perfect moral knowledge.

Why giving children rules and boundaries is a mistake

Children are not born knowing the truth, so we should tell children our best theories, explain why we advocate certain forms of behaviour and not others, and try to persuade them through reason of the truth of our own ideas, but not coerce, manipulate or in any way pressurise them into enacting our theories. For our theories may be false: even becoming a parent does not confer infallibility upon us!

“There are some issues on which I am authoritarian”

Coercion is stressful because it conflicts with most people’s wider ideas about morality, human relationships, and how to run a society, etc. Unless one mentions children or parenting, everyone agrees that consent-based solutions are better that coercion every time. That theory is held on some level by most people. They just suppress it in their parenting.
