"Dirty Mouth? Clean it up with orbit gum."

I feel that if an author wants to convey a certain situation, it may make the book more realistic if obscene language is used. However, the author needs to understand that using this language for any other purpose than to make a scene more life-like can cause controversy and possibly offend the reader. If the author feels that obscene language is necessary to deliver the same shock as the original scene or dialogue, than obscene language could probably have a place in the book. Although obscene language can be used to deliver shock and provoke a strong reaction in the reader, there is a fine line between what is appropriate and inappropriate.
