Former Republican presidential candidate Rick Santorum railed against the exclusion of conservative Christianity from education in an interview with American Family Association radio host Bryan Fischer on Tuesday, Right Wing Watch reported.

“I think we should start calling secularism a religion,” Santorum told a grinning Fischer. “Because if we did, then we could ban that, too, because that’s what they’ve done: they’ve hidden behind the fact that the absence of religion is not a religion of itself.”

The former Pennsylvania senator, who partnered with Fischer’s organization in the making of his newest “docudrama,” argued that secularism has “moral teachers” that should classify it as a religion.

“The idea that, if you take religion out of the public square, you take the Bible out of the classroom, that that’s neutral. Well no, that’s not neutral,” Santorum argued. “It’s a different worldview.”

According to Think Progress, Santorum has said that the film, One Generation Away, would attract protests from secularists, saying, “I’m a dog whistle to the left,” and calling it an opportunity to further his call to prioritize the Bible in school curriculums.
