Sowell contended that there has been an unchanging subculture going back centuries. Relying on Grady McWhiney’s Cracker Culture (1988), a flawed historical study that turned poor whites into Celtic ethnics (Scots-Irish), Sowell claimed that the bad traits of blacks (laziness, promiscuity, violence, bad English) were passed on from their backcountry white neighbors. In Sowell’s odd recasting of the hinterlands, a good old eye-gouging fight was the seed of black machismo.
