Maybe he or she assumed that people would understand the incredibly obvious reference to a villain in one of the most popular movies of all time rather than cry like babies and play the race-card?
As someone else pointed out quite recently but you seem to have ignored; there are an awful lot of folk who don't follow Batman. Shocking, I know.
Moreover, it's not really important whether or not the primary slant is a Joker slant. Putting white face on a black man is going to look like whiteface. Do you really have a hard time understanding why? I'm a big fan of that Batman film and when I saw that picture the first time I had two gut reactions; (i) oh cool, a batman reference (ii) oh man, whiteface?
I think the real issue here is that Obama fans know that "How dare your mock Dear Leader!" won't go over with the public as well as "That's racist!!!!!!!!!" will, so they're going with the latter.
With the possible exception of direct incitement to violence, I support complete free speech rights. Painting a white face on a black man's face looks like whiteface. It shouldn't be banned, it's just stupid and/or inconsiderate.
Look at it this way... That picture might remind some people who have been genuine victims of racism of whiteface, and thus call up painful memories of injustice. This, in itself, is inconsiderate. Moreover, anything that unnecessarily stokes the flames of an ugly racist past is divisive. Unless your intention is to cause a racial stir and offend some folk, it's pretty stupid to call whiteface to mind.
Wasn't there a whole bunch of pages with George Bush and a chimpanzee making similar expressions? If they did it with Obama, it would be called racist.
Probably because 'monkey' and other such words and concepts have traditionally been used as a racist insult towards blacks and not whites.
Is this really difficult for you folk to understand?
