Family Research Council Tony Perkins let loose with a rant about how President Obama isn’t a real Christian on his “Washington Watch” radio show Friday to once again claim that a Supreme Court decision on gay marriage could lead to a full-blown revolution and “literally split this nation in two.”

It all started when a caller, John, told Perkins about a discredited conspiracy theory that Egyptian investigators had uncovered evidence that proves President Obama is a member of the Muslim Brotherhood. He said that Obama “is a pure Muslim” who “doesn’t want any Christianity [sic] to be uprising here like the Muslims are,” adding that Obama was trained by his father “how to be a devil and a Muslim and how to hate the white people and how to hate Christianity and how to hate others.”

Perkins responded by claiming that while he can’t say for sure whether Obama is “a follower of Allah,” he knows that Obama is “deferential toward Islam and has been hostile to orthodox Christianity.” He also cited bizarre comments by Franklin Graham about Obama’s family.

He eventually focused on the caller’s comments about the need for a Christian “uprising,” which he said could be triggered by a Supreme Court ruling in favor of marriage equality: “I think, John, your point about Christians rising up, I think we are getting close to that in this country as we see increasingly this growing hostility at the hands of our own government toward Christianity and I think especially if the court imposes upon the nation a redefinition of marriage. I don’t think the nation is going to accept it, I absolutely don’t, and the conflict that is going to come as a result of it.”

Interestingly, one poll taken last year found barely any support for Perkins’s call for a revolution.

Later in the program, Perkins said that the FRC will be leading an effort, starting on “the Monday after Easter, [of] twenty-one days of prayer and fasting for our nation, that leads right up to the Supreme Court’s oral arguments on the marriage cases, and we need to first be praying, we need to repent as a nation, but then we’ve got to get up out of our prayer closet and put feet to our prayers and be involved.”
