It's never pretty. Case in point. I'm no fan of Al Sharpton, whose overblown claims of racism diminish the charge (in the exact same way as rightwing claims of antisemitism), but as they say: even a stopped clock is right twice a day, and in this case I think the Reverend has it right. There is so much wrong with this sick cartoon it's hard to know where to start, so the racism of it is as good as any. But I would also add the obvious point that the shooting of this poor chimpanzee who was a PET, and the horrible mauling of the owner's friend is a multi-layered tragedy that has no place on anyone's cartoon page.
UPDATE: Of course, as we World-O-Crappers well know, wingnuts are at their funniest when they are trying to be serious.
