On his September 14 radio show, Fox News host Bill O'Reilly insisted that the secular progressive movement “would like to have marriage abolished ... because it is not diverse enough.” He explained, “That's what this gay marriage thing is all about.” O'Reilly then warned of the possibility of “poly-amorphous” marriage, in which “you can marry 18 people, you can marry a duck.”

From the September 14 broadcast of Westwood One's The Radio Factor with Bill O'Reilly:

O'REILLY: The secular progressive movement would like to have marriage abolished, in my opinion. They don't want it, because it is not diverse enough. You know, that's what this gay marriage thing is all about. But now, you know, the poly-amorphous marriage, whatever they call it, you can marry 18 people, you can marry a duck, I mean --

LIS WIEHL (co-host): A duck? Quack, quack.

O'REILLY: Well, why, you know, if you're in love with the duck, who is the society to tell you you can't do that?

This is not the first time that O'Reilly has expressed concern about the threat of marriage with farm animals. He has repeatedly warned that in the future, "[y]ou'll be able to marry a goat."
