But the "black man playing white" is at best subsidiary to the "Obama = crazy sociopath" meme. The Joker is very topical, but hardly racial. If it was about racism, why not just choose anything else with a white face? Why not just parrot old vaudeville themes? I can't speak to any such themes during the campaign, but what the hell is "black man clown for the white" meant to be? Is this a common meme?
