Your missing the point.
It isn't only "parents." It is all adults in the group.
I had hoped to do this without having to type out Dawkins' whole idea but, guess not.
From Page 174 of The God Delusion.
My specific hypothesis is about children. More than any other species, we survive by the accumulated experience of previous generations, and that experience needs to be passed on to children for their protetion and well-being. Theoretically, children might learn from personal experience not to go too near a cliff edge, not to eat untried red berries, not to swim in crocodile-infested waters. But, to say the least, there will be a selective advantage to child brains that possess the rule of thumb: believe, without question, whatever your grown-ups tell you. Obey your parents; obey the tribal elders, especially when the adopt a solemn, minatory tone. Trust your elders without question. This is a generally valuable rule for a child. But as with the moths, it can go wrong.
Any adult in the tribe, seeing a child about to put its hand in a fire should instantly shout "STOP." There is no reasoning. There is no discussion. There is no psychological growth. Dawkins point is that the child which obeys instantly has a survival advantage over the one who says "you don't mean me, do you?" and proceeds to burn his hand. With luck, the dumb ones drop out of the gene pool early on.
Unless the Supreme Court awards them the presidency!
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.
