I think that saying that the words are in the bible is a childish excuse. Everyone knows what context is.
The word whore is the bible as well ... doesn't mean it's OK to call someone one
I do sometimes curse, doesn't mean I think it's a good / ok think though.
...and if I hear someone curse a lot (like in half their sentences), I am incapable of taking them seriously.
We are (hopefully) reasonably smart creatures after all, we should be able to use proper words to explain our feelings without resorting to profanity
