I recently discovered that my Ancestry.com ethnicity estimate is 66 percent European and 32 percent African. It confirmed the rough percentages that had been rattling around in my head for all these years. It also reminded me of the constant social media drumbeat from liberal academicians and journalists who lament the emergence of a transcendent awareness that would relegate our current binary race-consciousness to the rubbish bin of history.

Admittedly, not everyone interprets the growing population of self-identified multiracial Americans as a critical mass of spiritual enlightenment. Witness the first mulatto president identifying with merely one-half of his racial heritage, rarely mentioning the other.
