"If you can't manage courtesy, try silence."

Previous Quote

Satanism advocates practicing a modified form of the Golden Rule. Our interpretation of this rule is: "Do unto others as they do unto you"; because if you "Do unto others as you would have them do unto you," and they, in turn, treat you badly, it goes against human nature to continue to treat them with consideration. You should do unto others as you would have them do unto you, but if your courtesy is not returned, they should be treated with the wrath they deserve.
