Corporal Punishment is Wrong

You shouldn't hit your children. Aside from the evidence that corporal punishment is ineffective at correcting bad behavior, that it reinforces aggression and aggressive behavior, that it makes your children fear you rather than love you, and that it teaches them that violence is a viable solution to their problems, hitting or beating your children (or anyone outside self defense in a life or death scenario) is savagery and brutish. If you can't teach someone right from wrong without hurting them, then you're not fit to teach anyone right from wrong.
