Y'know SubZ, I think this section of the Wikipedia article sort of sums it up:
Usage in the United States
While a small cohort of Americans are aware of the term's much reduced offensiveness in Ireland and Australia, the word cunt remains in America the one word that is so offensive as to be customarily unspeakable. The usage is quite different from other English-speaking countries; in the United States the word solely refers to a woman's genitals or to the woman herself.
It's not a question of WHY or WHY NOT. If you want to use the word, by all means, do so, but don't be surprised if you find women who become furious with you. Don't use that word around women you don't know, or you will risk offending them. For the reason why, I refer you back to Wiki:
Referring to women
In referring to a woman, c*** is a derogatory or abusive term, often considered the most offensive word that can be used in this context. It can imply that the named person is extremely nasty and unpleasant in a way that exceeds the vehemence of the word bitch. In the film One Flew Over The Cuckoo's Nest, the central character McMurphy, when pressed to explain exactly why he doesn't like the tyrannical Nurse Ratched, says: "She's something of a c***, ain't she, Doc?" It can also imply that women are useful only for having vaginas and thus serve no purpose save sexual gratification. Comedian David Cross uses the word to describe Paris Hilton and Nicole Richie in his 2004 stand-up comedy album titled It's Not Funny.
It is sometimes used, somewhat less abusively, in vulgar reference to supposed female inferiority: "Why should I let some dumb c*** tell me what to do?"
In 2004, University of Colorado president Elizabeth Hoffman fanned the flames of a football rape case when, during a deposition, she was asked if she thought "c***" was a "filthy and vile" word. She replied that it was a "swear word" but had "actually heard it used as a term of endearment". A spokesperson later clarified that Hoffman meant the word had polite meanings in its original use centuries ago. In the rape case, a CU football player had allegedly called female player Katie Hnida a "fucking lovely c***".
It's got nothing to do with what YOU or your mother think of the word. You've got a lot of women on this board saying, "We find the word offensive." In our nation that word, along with quite a few others, is considered NASTY, end of discussion. It's a culture thing. Yes, it is a slang word for a body part, but that word, in OUR country, has come to mean something else. Simply put, it's not the word, it's what the word means.
It's like boobs. Why should it be okay for a man to go shirtless and not a woman? Some extra fat deposits? No, it's what breasts represent to those people who make obscenity laws.
