And God spoke all these words, saying, "I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery. ...You shall not bear false witness against your neighbor."
If I cannot slander or bear false witness, then sarcasm is ruled out too. "Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person." Colossians 4:6 No slander, no ad hominem attacks, no insults. The guiding rule is to build up rather than tear down.
