I'd say that desensitisation to profane language is a good thing, as it doesn't make any sense to be offended by a single word.
Of course, the problem with "desensitization" is that obscenities stop being obscene if everyone in society agrees not to be offended by them!

Thus, if I hit my fingers with a hammer, it is far more emotionally satisfying to yell "Oh f*ck!" than "Oh, fudge!"

But if every English speaker became 100% "desensitized" to "f*ck*, and parents stopped scolding their children for using this word, then "Oh, f*ck" would lose its power -- it would no longer give "cathartic satisfaction" after you've hit your finger with a hammer.

And yelling "F*ck me harder! F*ck me deeper!" during sex would sound the same as "Make love to me with more vigor and speed!"))))

P.S. In today's English, the phrase "to make love" is (always) a euphemism for "to have sex" or "to f*ck," and really has no other meaning.

But in 19th-century English, and perhaps even until the 1940s or 1950s, "to make love (to someone)" meant the same thing as "to flirt with" or "to court."

Thus, in older literature (before the WW2 era), it was quite normal to see a woman asking a man: "Sir, are you making love to me?"

Which, then, was understood to signify "Excuse me, Mister, it sounds as though you are trying to be flirtatious -- is this your intent, or have I misunderstood you?"
But nowadays it can only mean "Are you putting your penis in my vagina?"
