If beating children was so effective, and it worked so well, why did he ever have to do it? If everyone feared and respected authority because authority figures beat you, why did it still happen? If beating was such an effective, respected, and beloved strategy, why has it not carried over?
Beating children as a deterrent is for those who have no clue how to be respected, A leader who is respected because he has the authority to beat is really not respected.
(BTW, before anyone takes exception with my verb, "beat", I'm just borrowing it from the post I quoted.)
P.S. I have two grown children who are well-adjusted, successful, hard-working adults who have become great friends with my wife and me. They hang out with us for no other reason than we all love spending time together (their spouses included), and they have no problem asking our advice on things. We never spanked them, because we put so much effort into caring for and nurturing them. We spent time with them. We talked to them. We took an interest in their activities. We were never too tired to listen to or help them. Their fear was disappointing us. You know...parenting. It takes a lot more time, love, patience, commitment, and work than beating, but the end result has been much more rewarding.
