On "acting white"

John McWhorter has an interesting review of what looks to be an important new book on the pernicious conception of black authenticity, and how it feeds into the rejection of scholarly achievment as "acting white":

It was the demise of segregation, of all things, that helped pave the way for the “acting white” charge. With the closing of black schools after desegregation orders, black students began going to school with white students in larger numbers than ever before. White students were often openly hostile, and white teachers only somewhat less so. Black teachers and administrators from the old black schools often lost their jobs. Unsurprisingly, black students started modeling themselves against white ones as a form of self-protection.
