Hi. 

Interesting question.  I'm working on a post regarding this exact topic.  I should finish it within the week or so. 

Not a fan myself. 

i'm not sure if i fall into the christian category, per se, but the way i see it is this: as long as you're using words in a good way, and not for harm, there is no problem.

e.g.  kate, you are a fu@#ing amazing person. (that's the good way)

or fu@# those starving kids on those commercials! (that's the bad way)

if you're using those words to enhance your vocabulary for the good, then go at it! if not, then it's just as bad as saying screw those kids. or who cares about those kids. either way you're saying the same thing.

there is no such thing as a "bad" word and a "good" word. whether they are bad or good depends on the context in which you use them.

at least that's how i see it =)
