It has nothing to do with a comment being PC and everything to do with nationalistic flamewars that have popped up in the past, e.g. the one that involved Germany and Greece. The purpose of moderation isn't to police opinions or thought (I think this is obvious by inspection) but to keep this a civil place where people have something interesting to read instead of some shitheap like comp.lang.lisp or #startups on Freenode.
