Professional Opinion
The United Nations Committee on the Rights of the Child defines physical punishment that causes any degree of pain and discomfort (even light) to be abuse. They argue that eliminating corporal punishment of children is “a key strategy for reducing and preventing all forms of violence in societies”
This statement was extended by me to 'any contact' make it obvious they were on a slippery slope when talking about physical acts such as spanking or corporal punishment and linking such with pain or discomfort. Soon one can interpose 'unwanted' (child view) for 'corrective' or 'punishment' (authority view) and 'touching' for spanking.
All of these forms have been used from one perspective or another over the past half century.
So you can say I've argued any contact and unwanted contact instead of corporal or necessary or appropriate punishment since they both lie on interactive and degree continuum.
My view is it is in our nature to use physical, verbal, and temporal means to 'instruct' our children. Any construction for discipline need have its parameters worked out very carefully before that construction becomes a norm for any society. I think some physical, mental, and environmental control mechanisms can and should be applied to those for whom we are charged to help get to productivity.
I'm just not satisfied with our current discussion whether physical treatments should be sanctioned out of existence for our use in getting children to productivity. I see it focusing on authority, punishment, versus support for those responsible for doing the getting to productivity work. Instead we should encourage, reward, those who produce productive adults with tokens and encouragement without use of physical or coercive means.
