Years ago, I resented that certain Anglo-Saxon words of my ancestors were considered "obscene", while their Latin equivalents were not. For example, "vagina"and "pinus" are "allowed", but their Anglo-Saxonism are not.Then I realized that, in a culture heavily infiltrated by Anglo-Saxon heritage, AS words are the "private words" that lovers can speak to each other, while the Latinisms appear too formal. And the real reason for the public attitude became evident to me, and I agree with it.
As Flip Wilson's friend, Geraldine, used to say, "You don't know me that well!" We're not close enough that you should use private words for private parts and private acts, as if we're are!
And I was glad, recently, to read that Jonathan Winters, one of my favorite comedians, and a great clown, had scolded so many of the standups who use liberally use this language to get laughs. People who laugh at them don't realize that these snottynosed millionaires aren't really the chums of their listeners, but acting like the prototypical "high school tease".
That's the general objection and unrealized liakiness that includes the F-word, along with many others. The other object and leak is particular.
"I hate this f--g heat." "What a f--g car this is!" "I'm f--g sick of this!" ETSETTERY.
Dig? The term is PEJORATIVE! It describes something to be disliked or hated or avoided or scrapped. But how a PEJORATIVE adjective CONNECT with its applied noun?
I long ago decided that I don't believe in "The Subconscious". But I very much believe in THE SUBLIMINAL and in the effect of the SUBLIMINAL upon us, and particularly so with SUBLIMINAL LANGUAGE.
Do these speakers know they are telling themselves that THE EROTIC ACT is to be disliked or hated or avoided or scrapped? Do they really mean this? Why don't they just choose ABSTINENCE?
For example, the S-word deserves the first objection and type of leakiness. Excrement or human waste really is something to be rid of, and it's normal to feel so. The opposite feeling was categorized by Freudians as "anal rententive". So I think you should consider the company when you use the S-word. But I don't think you're hurting yourself by uttering it, as I think you are when you use the F-word.
Ethical is as ethical does. And the doing especially involves speaking.
