Why are we discussing this now? It has been illegal for years to chastise children by smacking, spanking or beating them.
I was born in 1951, my parents were convinced that it was possible to bring children up without physical correction, but on three occasions that I remember either my sister or I had our bottoms smacked. Mummy having rather stupidly said, "If you do that again, I will smack your bottom!" then found herself in the position where she felt forced to carry out her threat.
I doubt three isolated incidents in a loving upbringing damaged either of us, but that has in no way turned me into a believer in corporal punishment of any kind. I remember very, very clearly my parents' relief at the abolishment of capital punishment.
Children who grow up without love, empathy or even just ordinary kindness will, in most case be uanable to show others these traits.
The unforntunate thing here is that no-one seems really to have addressed the problem of how to deal satisfactorily with the many occasions on which a child just will not do as he or she is asked or told - often thereby running a risk of hurting themselves or others.
Avoiding, quite rightly, smacking children has led some parents (and teachers) either to allow their children to do more or less as they pleased all the time, or led them to use other forms of discipline that may not really be any healthier or better than smacking.
A lot of my generation, given the choice as a child between having their bottom smacked or having to listen to mummy or daddy going on, and on, and on about how naughty they had been would greatly prefer the smacked bottom to the lecture.
