In Sellout: The Politics of Racial Betrayal, Harvard law professor RANDALL KENNEDY provides more of the provocative thoughts that fueled his previous works and insists on a more stringent definition and examination of the whole notion of racial betrayal. (He himself has been accused of being a sellout by his critics in the African-American community.) Kennedy challenges Barack Obama's assertion that being black wasn't so much a conscious choice but an inevitability. He also spends an entire chapter explaining that U.S. Supreme Court Justice Clarence Thomas' questionable stand against affirmative action (while having benefited from it) doesn't make the high court's second black justice a "sellout." Kennedy speaks in Atlanta at the Literary Center Wed., JAN. 30. For a review of Sellout, click here. Free-$10.
