Swearing vs. Insulting

I believe FCY did not claim that WDF cannot swear, but that he cannot insult. Anyone can dive into a dictionary (or heck, even Wikipedia: http://en.wikipedia.org/wiki/List_of_swear_words or http://en.wikipedia.org/wiki/Foreign_profanity). Anyone can remember the list and *boom* you can now spew profanities anytime, anywhere. However, insulting your adversary, especially without the use of any explicit swear words, would be a much higher art.
