It's one thing to hold opinions as blatantly offensive as gloating over the death of a human being, it's quite another not only to state it in public but to feel compelled to do so. The whole thing has a "stick a finger in the eye of the
bourgeoisie" aspect to it that is one of the intellectual left's least attractive cultural features, and to attempt to rationalize it with simple falsehoods as Greer did compounds the sin. She may or may not be above us but she certainly ought to be above that.
Clearly she is not. And so we are left not with the image of a brave iconoclast bucking a trend, but of a disagreeable little girl sloshing paint over something beautiful so that no one else can enjoy what she is incapable of appreciating herself. That is very sad, but not very rare, behavior.
