My parents moved us to Utah when I was ten, and there I became so used to the Mormon habit of not swearing that even into my twenties when I was in graduate school, I struggled with books and movies that I was required to watch/read for my studies that had bad language in them.
I've written hundreds of thousands of words during the past 50 years, but I've never written the f-word. I don't need the word to communicate effectively or to get published. The English language is rich with so many other delightful, juicy, descriptive, and provocative words.
To me, the vulgarity in the novel was not its language. What truly makes me cringe -- the most vulgar and obscene things in life -- are humanity's ubiquitous displays of unrelenting greed, hatred, intolerance, and the unquenchable need of people to make war.
It would appear that there is a "dose" of swearing that works best. If you swear too much it reduces its benefit, but if you do not swear at all, you may not have as a high a pain tolerance. Swearing seems to have a protective effect -- to a point.
I appreciate the occasional well-meaning attempts to find sanitized alternative terms that preserve some of the flavor of the old standards, but sometimes there's just no replacement for le f-mot juste.
