Why is kunt such a bad word?

The word in question refers to more than just the female genitalia. Another connotation for this word is: A person (usually but not necessarily a woman) who is thoroughly disliked. Moreover, it means: Insulting terms of address for people who are stupid or irritating or ridiculous. When you think about it, all words, every single one, in any language, are completely neutral in and of themselves. In fact in and of themselves, they are utterly without meaning or significance of any kind. They are spoken symbols; metaphors that stand for something else. The question becomes, as explained above, a matter of common usage and common understanding. What is really interesting is that we humans reserve, very deliberately and almost reverently, a collection of words out of our huge lexicon that are dedicated to functions of shock, hatred, revulsion, division and emotional assault. It is not the words at all. It is the nature of the human beast. Cun* means many things, like a females genitalia, like pregnancy, it can mean an extremely unpleasent or objectionable person, it can mean an objectionable object or item. Cun* can mean an unpleasent or difficult experience. Or a woman as a source of sex.
