It’s a parlor game for progressive nerds: Take any conservative attack on Obama, assume racism, and then connect as many dots as you need to in order to get from point A to point B. Here it’s Obama = Joker; Joker = terrorizes city; terrorizing cities = stereotype of blacks; ergo, Obama = stereotype of blacks. It’s like “Six Degrees of Kevin Bacon,” but with political benefits. And as always with these things, the ease and almost eagerness with which the author perceives the nastiest racial stereotypes is unsettling.
