The idea that there is such a thing as right and wrong, and that we should all strive to do right, is important in TCS theory and practice. So is the idea that we are all, parents and children alike, fallible (i.e., we can make mistakes).
The idea that children can do no moral wrong is a positively frightening misconception of TCS. It implies that they are born with perfect knowledge in the sphere of morality, or that they guess the truth the first time. But that is no more likely than that they would guess the true theory of physics the first time. Children are bound to make moral mistakes, no matter how they are raised. They do not have perfect moral knowledge. It is vital to understand this, otherwise you will be failing to give your children the benefit of your moral wisdom, and the results could be catastrophic.
So what are the implications? Look out for more on this subject soon, including an article about how the TCS position differs from the conventional one, and why this sometimes results in the above misconception.
