Today on “The 700 Club,” Pat Robertson went on one of his patented rants about anal sex, arguing that he will never change his mind about gay marriage until someone proves that anal sex can lead to pregnancy. Robertson told a viewer who wondered how gay people can identify as Christians that “the gays wants to control everything.”

“This is part of the left-wing agenda,” he said, “to do away with Christian values and to substitute for Christian values the progressive concepts of morality.”

“You tell me if anybody, if you show me one couple that conceived a child through anal — through anal intercourse — just show me one in all the world, and I will say, ‘I agree with you and you are right.’ Show me one. There are 8 billion people, 7 billion, show me one time when a child was conceived by that kind of sexual activity,” Robertson said. “It is unnatural, I’m sorry.”
