“ It is, indeed, one of the basic moral blindspots of American conservatism that its intellectual and leadership energy have never been focused in a proactive way on America's racial-caste legacy. This represents a fundamental moral crisis of modern American conservatism.... American conservatives typically ignored the authoritarian and violent racial-caste practices and values arrayed against black Americans in southern states where the vast majority of blacks live. On the other hand, American conservatives have, throughout this century, often embraced freedom movements elsewhere in the world --in Europe, Latin America, East Asia-- but always firmly resisting a proactive embrace of the black American civil rights movement as a bona fide freedom movement fully worthy of their support. So it is in the shadow of this dismal record of mainstream American conservatism vis-a-vis black Americans' long and arduous quest for equality of status that new black conservatives have emerged. ”
