Well, I don't know about that. The nurturant parent outlook is supported by modern scientific views of child development and how the mind works. It doesn't ever consider harm to be a function of good. As Lorelei noted in a comment below, it's how humans lived for the vast majority of our history and probably why we survived when other hominid species that were less pro-social did not. Trying to understand another perspective logically and not just demonizing them as crazy isn't the same thing as saying that both sides have validity.
