Is it necessary? I think not.
I spend much of my time reading. I don’t read fast, I devour a novel. Almost everything published in our current era has profanity. In some there is little else. For years I’ve suspected profanity is a sign of illiteracy, having a vocabulary too small for the world he/she lives in.
James Fenimore Cooper bears that out in his book The Prairie.
I read four chapters of this book before going to bed last night. The protagonist, the trapper, and his friends have been captured by the Sioux. If ever there was a time for profanity this might have been it. But there is NONE. The man is able to express himself with the words found in any dictionary.
America seems to be growing more ignorant with each subsequent generation.
