Nowadays nobody seems to care very much if their behaviour could be labelled "vulgar". They carry on doing their own thing regardless, and if anyone disapproves, too bad. Seeing something as vulgar has itself become vulgar.
But my parents had a long list of things they deemed vulgar - not wearing smart enough clothes, not mowing the lawn often enough, not using a tablecloth, not washing up straight after a meal, to name a few - and they policed this code of vulgarity strictly.
Of course what "vulgar" really meant was lower-class or under-educated. It meant what they did on council estates or in factories. It meant the behaviour of people with no sense of decorum or etiquette. It meant those too dim to have any sophistication or good taste.
But that's all changed. Now the very suggestion that someone is being vulgar is seen as pretentious, snobbish, superior. It's seen as a mean attempt to spoil someone else's pleasure. It's seen as blinkered, old-fashioned prejudice.
I suppose my parents' strictures had some positive effect, however absurd some of them were. I may have lived my whole adult life without using a tablecloth, but nevertheless I've picked up a sense of "doing things properly" rather than doing them any-old-how, which is probably an advantage.
I guess the idea of vulgarity still lives on in other guises. Today, instead of saying something is vulgar, you say it's embarrassing or cringey. Or you say the person is attention-seeking. Or you complain that everything is being dumbed down.
And dumbing things down is surely the height of vulgarity.
