At the Raleigh News and Observer, Barton Swaim suggests that Trump used political correctness to appeal to his followers by campaigning against it; Swaim suggests that the tactic may well have backfired. Here’s a snippet (emphasis added):
That feeling of delegitimation, of not being able to state one’s beliefs without attracting accusations of bigotry and backwardness, isn’t something most Americans will put up with for long. Many of them felt gagged and irritated, and Trump shrewdly named the thing that troubled them: political correctness. A lot of people fell for it. And in falling for it, they made two disastrous mistakes. First, by promoting political incorrectness as a remedy to the taboos they rightly detest, they gave us a man so loathsome as to make those taboos seem almost sensible. In the saddest irony of this deeply strange election year, Trump’s supporters have managed to enhance the credibility of political correctness: Given the choice between political correctness and the bigoted tirades of a dirty old man, I’ll take political correctness.
One more time, persons who complain of political correctness demand permission offend without penalty.
