"In other words, the father believes that an object, not the hand, must be used when administering discipline."
So he thinks that using a tool to do the beating somehow fools the kid into not blaming dad for the pain? If you haven't raised your child better by this age, your methods don't work and you should seek teaching. Kids who get beaten do NOT feel more loved. I feared my parents and resented them and they did not make up for it with enough praise or encouragement or support, and they lost their children. My family is scattered and does not communicate. We were not beaten enough to get bruises or cuts, fyi. It was just "spanking."
