But I think there's a lot of judging of parents who do use corporal punishment. Corporal punishment for real offenses (and that does not include dropping a ball or inconveniencing a parent) is not child abuse. It's painful, not pleasant for the parent or child, but in some cases, for some kids, it's the best way to make a believer out of a kid and produce a happy productive adult respectful of the rights and feelings of other.
Really, how does it do that?
What if your kid gets hit and, 30 minutes later, thinks, "I can take that?"
