Distressing though cultural vandalism may be, it is, and has always been, widespread: in UK under Henry VIII and again under Oliver Cromwell "graven images" were destroyed in churches. Classical statues and Oceanic images were mutilated and destroyed in the name of morality and Christianity, statues of unpopular politicians are usually destroyed in revolutions. I like to think a mature society is one that can continue to display the artifacts of its past, whether those conform to current prejudices or not.
