"Because the point of P.C. is not and has never been merely about any of the items that it imposes, but about the imposition itself. Much less is it about creating a definable common culture or achieving some definable good. On the retail level, it is about the American’s ruling class’s felt need to squeeze the last drops of voter participation out of the Democratic Party’s habitual constituencies. On the wholesale level, it is a war on civilization waged to indulge identity politics."
