College today functions as middle-class finishing school, the gate and key to the world outside the service industry. … [A]cademia is the font of moral instruction in American society, a decade or so upstream from the mass media. We learn at college that “people of color” is the proper designation for non-whites and that “LGBTQA+” is the proper acronym for the broader gay community. This is the twenty-first-century version of knowing which fork to use when navigating a multi-course meal. Where dining etiquette expresses refinement and discipline, politically correct behavior demonstrates a commitment to diversity and inclusion.
