I guess you may ask why Sin was created, since we are not supposing to Sin. I think some one started saying words or using words they made up. When people starting using these words they had such a mean facial expression on their face, that the words had to be interpreted as bad words or swear words. I think you must pick your audience, and if you feel comfortable using any word and if it does not offend your audience then by all means use them. Take care.
