I see nothing wrong with the occasional (or in my case, not so occasional) use of profanity to make a point in conversation, or in the use of the words in the dialogue in a piece of fiction. Real people do swear. Not all of them, but some. However, the relish with which some bloggers and (usually anonymous) responders to the blogs use profanity on the Internet never fails to amaze me. It often seems to serve no purpose and simply sounds stupid.
Is it their desire to be seen as angry artists, the misunderstood geniuses railing at the world? Or is it merely an insult to and degradation of our language by those who are not intelligent or imaginative enough to use it correctly?
