Daniel Patrick Moynihan, a sociologist and socialist politician, wrote an article called "Defining Deviancy Down". The point of it was that as we become more and more politically correct, we change the definition of deviancy to include less and less. Because it's mean to call a deviant a deviant. And when you reach the point where deviance means nothing, then your civilization is dead because you no longer have any standards to uphold and no means for progress.
Unless Japan does something about this sort of crap, their civilization is going to die before ours.
