The message you convey to everyone when you use profanity is, "I have lost all use of common sense - do no try and communicate with me logically." Sometimes the use of profanity is warranted ... even, dare I say, necessary. Situations such as bank robbers threatening tellers; soldiers dealing with each other and opposing forces under fire; a firefighter trying to clear a burning building; anyone dealing with telemarketers - these are all situations when you don't want any backtalk, you just want results.

It is a good thing when you are consciously trying to convey the shut-up-and-do-what-I-say subtext. It is wholly another when you accidentally broadcast your lack of self-control and/or ignorance of the subtleties of communication.

But don't worry - you won't see very much of that here.
