I think a foundational corollary to this is that somewhere along the way, maybe in the 80's, our society decided that kids ever feeling shame was an irreparable emotional trauma that would scar them forever. While of course I believe people should never be shamed or feel shame for who they are, sometimes letting kids feel shame because of the things they do can be a valuable and lifelong lesson. It's a core part of learning how to be a functioning, moral person in society. These parents who never want their kids to ever feel ashamed of anything they do are not only doing their kids a grave disservice, they are disserving society at large by raising sociopaths. Sometimes shame can be extremely instructive and valuable to forming emotional intelligence and personal morality.
