I think there's a very limited period of time in which corporal punishment is appropriate, or even does any good. I appreciate a smack on the hand that reaches for the hot stove or the Ajax, provided it's attached to a kid too young to talk much or think rationally. But I remember arguing my parents into corners they couldn't get out of at age eight. At that age, I was also baptized by the church they raised me in, defining me as of the age of moral responsibility. After that age of insensibility, corporal punishments tend to only create resentments.
Kids learn to stand up to pain after awhile, anyway.
I've intentionally done things I knew would result in getting hit, if I were caught. My concern was not getting caught. The threat of pain isn't as much of a deterrent, once you know you can withstand it. And the more frequently it happens, the less and less it means. Basically, what my post was about was that I thought what Jeb Bush said was rather stupid.
