You would not believe the number of sensitivities that have to be kept in mind in public discourse. I once got mad at some Texas legislators over a spectacularly pea-brained stunt and referred to them as “a bunch of droolers.” I was promptly served with pamphlets from an outfit called the Society to Prevent Cruelty to Those Who Involuntarily Drool. (Very sad, actually, people who have had strokes often drool involuntarily.) People make fun of political correctness, but if you’re running for office, left-handed lesbians of Czech descent are out there, and they are touchy.
