A multiracial, single-cultural U.S. was an historical fluke. No other society has ever quite pulled that feat off—not Austria-Hungary, not Rwanda, not Iraq, not Yugoslavia. To ensure multiracial harmony, cultural unity (or what is now dismissively written off as the “melting pot”) was essential.

Yet the Obama era has reawakened ethnic chauvinism and multiculturalism in a way we have never quite seen before in recent American history. Who would have thought that in 2009, the racist firebrand, tax-delinquent, anti-Semite, former FBI informant, and conspiracist Al Sharpton would become the chief presidential advisor on race, or that the attorney general would refer to blacks as “my people” and the rest of the country as “cowards,” or that the president would urge Latinos to “punish our enemies,” or that something chauvinistic called “Black Lives Matter” would consider a corollary ecumenical “All Lives Matter” as racist, or that “white privilege” would be a slur hurled against the largely working white classes by mostly minority and white elites in academia, politics, journalism and the arts?

Coupled with years of open borders, a failure to enforce immigration laws, hostility to integration and assimilation, and racial preferences in hiring and admissions, the Obama administration in just over seven years has nearly achieved its aims of racializing the American experience to such a degree that everyone must now belong to his particular tribe first, and begrudgingly remain an American a distant second.

An example of our future is found in Rome around the early 5th century AD onward, when parochialism and localism reasserted themselves, as Civis Romanus sum was rendered irrelevant. I fear that self-segregation is already institutionalized, as people migrate to live with like kind in red and blue states. And states such as California have divided into two antithetical societies, in which an interior Fresno is about as akin to coastal Newport or Palo Alto as Somalia is to Switzerland.
