to carry your message across . There are some people in this world who understand only this language. What do you say ?
It's not only for those ^ people. The "shock value" that the F word carries makes it more worthy of conveying certain messages across with great effect. We have one example right in this thread*, the more people oppose the use of this word, the more "shock value" it has for these people and certain messages can be delivered very effectively to these people using the F word.
There have been some good researches done on this topic and now quite a few public speakers and other public figures use these kind of supposedly offiensive words in a "positive" way.
