Doesn't matter what someone "is". Slurs are slurs. Really don't see how calling someone a "cunt" is any better than using the n-slur or f-slur. (Except apparently those are censored here but "cunt" so I guess AP.net is okay with sexism, just as long as it isn't racist or homophobic sexism)
I get what you're saying, and to a large extent: you're right, but let's call a spade a spade here. She's the c-word.
