You cannot convince me that the F bomb is the best verb/adjective/noun/adverb/interjection for any situation
... just as you cannot convince me that it's the
worst. You find the f-word offensive because you were
taught that it's offensive, just as x_ethnicity is taught that y_slur is offensive or d_religion is taught that e_activity is blasphemous. Words in and of themselves only offend if you
let them offend — sensible people understand that the intent
behind words is what matters.
Do you sincerely believe that intelligence or maturity are related to breadth of vocabulary? If so, there is no point in discussing the matter further, as your fundamental misunderstanding of the human creature would make it a futile effort. I could, for example, say something like, "Folks with IQs and social maturity levels many standard deviations off the norm in
both directions use profanities, as do those everywhere in between," but it would be fruitless.
Regardless, a proclivity to devalue the opinion of those who swear indicates a manner of prudish intolerance which modern society needs to lose. Insert the work of George Carlin again. The point of all his "dirty words" skits is that taking offense to any word in and of itself is as nonsensical as any other human habit which has evolved into tradition (traditions being the root of many if not most of mankind's major conflicts, as it were).
