Well Holly I don't like the F word because I think it makes the love making in marriage that God intended to be a beautiful oneness between a married couple sound like something ugly and disgusting but this is only my opinion. The Bible has a Scripture that basically says: "The marriage bed is undefiled." Somehow to me that F word defiles it. But then that is just my opinion. And you are right we could basically make any word seem or sound like a cuss word depending on our tone of voice when saying those words. But I don't know how one officially decides what words are cuss words...or who gets to decide that.
