“Duck Dynasty” star and conservative icon Phil Robertson told a gruesome, vivid story on Friday about the hypothetical rape and murder of a family to illustrate the perils of atheism, according to audio surfaced by Right Wing Watch.

The website reported that Robertson made the remarks during a speech at a Florida prayer breakfast that was later broadcast by the conservative radio program TruNews.

From the Right Wing Watch report on Robertson’s speech:

“I’ll make a bet with you,” Robertson said. “Two guys break into an atheist’s home. He has a little atheist wife and two little atheist daughters. Two guys break into his home and tie him up in a chair and gag him. And then they take his two daughters in front of him and rape both of them and then shoot them and they take his wife and then decapitate her head off in front of him. And then they can look at him and say, ‘Isn’t it great that I don’t have to worry about being judged? Isn’t it great that there’s nothing wrong with this? There’s no right or wrong, now is it dude?’” Robertson kept going: “Then you take a sharp knife and take his manhood and hold it in front of him and say, ‘Wouldn’t it be something if this [sic] was something wrong with this? But you’re the one who says there is no God, there’s no right, there’s no wrong, so we’re just having fun. We’re sick in the head, have a nice day.’” “If it happened to them,” Robertson continued, “they probably would say, ‘something about this just ain’t right.”
