Comparing police brutality to hitting children makes no sense at all. Additionally, many people make the argument that they were beaten as a child so it's ok. Some will use any excuse to inflict pain on their child. Spare the rod, spoil the child. It's in the bible. We also have a talking snake in the bible. The bible says that if you see your neighbor working on the sabbath it's ok to kill him. Nothing replaces critical thinking. Don't blame your behavior on what you read or what happened to you. Physical pain is not teaching. You can change a child's behavior by spanking them but you will not help them to develop their character. You can only help develop a caring, loving child by exhibiting those traits yourself. Be a mentor. Use your words, not a belt. Be kind, not cruel. Lead by example. Stop being lazy. Teaching takes more time but that's part of your job description as a parent.
