"Bullying a child into submission is a coward's way"
There is a vast difference between bullying, i.e. real violence, and gentle chastisement when normal reasoning has failed,which most people are referring to here.
I don't suppose I struck my son more than half a dozen times in his life, never anywhere but on the buttocks, never hard enough to mark the skin, and never hard enough to hurt. He already had so much respect, not fear, for me that the very fact that I did such a thing was enough to show him how upset I was.
That was not instilling fear but as much a part of my love for him as the hug he subsequently got when all was forgiven.
Perhaps we should forget the emotive language and recognize that while no-one is advocating violence against children, or anyone else for that matter (I don't even care to watch boxing) there are genuinely held differing fields of thought on this.
