Cuss Words

Why have Christians banned so-called cuss words? What does the Bible say about this? Paul taught the Ephesians against unwholesome talk (4:29), a much broader term than a mere list of banned words. In fact it doesn't refer to individual words at all, but how we communicate. 1 Samuel 20 records Saul refering to Jonathan as the linguistic equivalent of a son of a b__. Okay, so we don't follow Saul's example. Jesus called Herod a fox and the Pharisees snakes and hypocrites, culturally equivalent to curse words in modern English. Paul called the former things dung, actually more like crap or s__ in the original language. The Bible also refers to men as that gender that p__ against a wall. Don't get me wrong. I usually find vulgarity offensive. However, there is also a fitting occasion at times. The New Testament does not give us lists of banned words.
