Francois at Prime Directive has this to say:
“Let me make one thing clear: spanking of children is sexual assault, there is no rational argument for spanking, and if you support spanking in any form you support sexual assault. People fail to recognize this in the case of children because child abuse has been the norm in child-raising in Western societies, and as the norm we are not predisposed to see anything wrong with it.
Furthermore, a majority of people have been spanked by their parents and will adamantly refuse to blame their parents for it, so they must defend spanking. I do not expect those people to come to their senses, because they have been damaged by their childhoods and are heavily invested in the belief that their parents loved them and would not have intentionally harmed them. Such people can hardly be asked to be objective about child-raising, and their opinions have no more relevance than the opinions of slaughterhouse operators on animal rights.”
