VICTOR DAVIS HANSON: Diversity Can Spell Trouble.

America is experiencing a diversity and inclusion conundrum—which, in historical terms, has not necessarily been a good thing. Communities are tearing themselves apart over the statues of long-dead Confederate generals. Controversy rages over which slogan—“Black Lives Matter” or “All Lives Matter”—is truly racist. Antifa street thugs clash with white supremacists in a major American city. Americans argue over whether the USC equine mascot “Traveler” is racist, given the resemblance of the horse’s name to Robert E. Lee’s mount “Traveller.” Amid all this turmoil, we forget that diversity was always considered a liability in the history of nations—not an asset.

Ancient Greece’s numerous enemies eventually overran the 1,500 city-states because the Greeks were never able to sublimate their parochial, tribal, and ethnic differences to unify under a common Hellenism. The Balkans were always a lethal powder keg due to the region’s vastly different religions and ethnicities where East and West traditionally collided—from Roman and Byzantine times through the Ottoman imperial period to the bloody twentieth century. Such diversity often caused destructive conflicts of ethnic and religious hatred. Europe for centuries did not celebrate the religiously diverse mosaic of Catholic, Orthodox, and Protestant Christians, but instead tore itself apart in a half-millennium of killing and warring that continued into the late twentieth century in places like Northern Ireland.

In multiracial, multiethnic, and multi-religious societies—such as contemporary India or the Middle East—violence is the rule in the absence of unity.

Well, luckily we have Social Justice types to remind everyone that they’re not supposed to get along.
