From The Searcher by Tana French (2020):
Over the last few years it’s been brought home to him that the boundaries between morals, manners and etiquette, which have always seemed crystal-clear to him, may not look the same to everyone else. He hears talk about the immorality of young people nowadays, but it seems to him that Alyssa and Ben and their friends spend plenty of their time concentrating on right and wrong. The thing is that many of their most passionate moral stances, as far as Cal can see, have to do with what words you should and shouldn’t use for people, based on what problems they have, what race they are, or who they like to sleep with. While Cal agrees that you should call people whatever they prefer to be called, he considers this to be a question of basic manners, not of morals. This outraged Ben enough that he stormed out of Cal and Donna’s house in the middle of Thanksgiving dessert, with Alyssa in tears running after him, and it took him an hour to cool down enough to come back in.
In Cal’s view, morals involve something more than terminology. Ben damn near lost his mind over the importance of using the proper terms for people in wheelchairs, and he clearly felt pretty proud of himself for doing that, but he didn’t mention ever doing anything useful for one single person in one single wheelchair, and Cal would bet a year’s pension that the little twerp would have brought it up if he had. And on top of that, the right terms change every few years, so that someone who thinks like Ben has to be always listening for other people to tell him what’s moral and immoral now. It seems to Cal that this isn’t how a man, or a woman either, goes about having a sense of right and wrong.
He tried putting it down to him getting middle-aged and grumpy about young people these days, but then the department went the same way. They brought in a mandatory sensitivity training session – which was fine by Cal, given the way some of the guys treated, for example, witnesses from bad hoods and rape victims, except the session turned out to be all about what words they were and weren’t allowed to use; nothing about what they were doing, underneath all the words, and how they could do it better. Everyone was always talking about talking, and the most moral person was the one who yelled at the most other people for doing the talking all wrong.
He’s afraid to answer Trey, in case he leads him wrong and gets him into all kinds of trouble, but no one else is going to do it. “Morals,” he says in the end, “is the stuff that doesn’t change. The stuff you do no matter what other people do. Like, if someone’s an asshole to you, you might not be mannerly to him; you might tell him to go fuck himself, or even punch him in the face. But if you see him trapped in a burning car, you’re still gonna open the door and pull him out. However much of an asshole he is. That’s your morals.”
