Once upon a time a Slave-Driver asked a Holy Book if slavery is righteous. The Holy Book quoted several of its passages calling slavery a divine blessing, ordained by the Lord.
Later an Abolitionist asked the Holy Book the same question. The Holy Book quoted several of its passages calling slavery a foul abomination, in defiance of the Lord.
Later still a Skeptic asked the Holy Book about those two opposite answers. The Holy Book said, “I am all things to all men.”
Moral: A meme’s gotta do what a meme’s gotta do.
