Whether walking down the street or watching film or T.V., we and our children are often subjected to a barrage of crude and offensive language. Some, including comedians, clearly think it’s funny to use such language for a cheap laugh and in response their audiences laugh as though it is. It’s not.
Their coarseness simply reveals their ignorance and poverty of language. Children learning it may think it’s acceptable, clever even, and may begin to adopt it.
I would want parents to avoid coarse language and to employ instead a richness of vocabulary which reveals the beauty and scope of our native language, thus encouraging their children to express themselves elegantly without the need ever to resort to profanities.
