Art Victimized Once Again

Is this the next step? In early times they'd just chop off the heads of those with power as documented in the painting of Marie Antoinette's head rolling into a basket in a museum in the Marais.

Now it seems the disgrace of disfigurement is more in vogue. It disturbs me. I enjoy watching the grafitti artists perform on the temporary walls of the Palais de Tokyo but when they piss on the art it makes all of their work illegitimate for me.
