Well I don't want to sound more cynical than the OP, but the surface is actually what matters in the broader social context. Without shame, human society would be a violent anarchy. Some people have relatively good natures, but many do not. That is not even a criticism. After all, one cannot be ashamed of nature - only of the inability to control it. Absence of shame is like power: it corrupts. So whatever we call PC, we need something like it. That is my view.
