That is a old rule, has been that rule since they were the Babylonian Brotherhood of the snake, Word is they dropped Babylonian so people would not make the connection. because they tie in with the serpent in the garden of Eden. They worship that serpent that gave them knowledge with disobedience to God. They hate God because Adam and Eve were cast out of the garden of Eden. Being lefties they blame God but forget it was the serpent that caused that to happen. lefty lack of logic goes that far back
