Is America Post-Racism?
Short answer: No.
CNN reports the latest study showing anti-black racism in action. It's one of those scenarios where a white says something horribly racist after the lone black leaves the room and none of the whites react. The beauty part of this study, though, was later asking participants who they wanted to be paired with on another exercise—the black who'd been dissed 'without his knowledge,' or the white who'd done the racist dissing. Guess who most whites chose.
It's reasonable to expect lots of folks not to speak up when hearing racist doggerel, even if they object to it. But to then choose the racist as a partner over the black he insulted pretty much settles the question.
