It has been 56 years since the Supreme Court struck down segregation in Brown vs. Board of Education. A new book, “Acting White: The Ironic Legacy of Desegregation,” puts forward the notion that desegregation's positive changes have come along with some unintended side effects. Stuart Buck, the book's author, argues that the criticism successful black students often receive from their peers – that they are “acting white” – is largely a consequence of how our schools were desegregated.
