In another edition of "SHUT UP, BILL O'REILLY," Bill slammed the makers of Glee for including a transgendered teen (played by Alex Newell) on their show. From the New York Daily News:

“Here's the problem with a show like this, though,” O’Reilly said in the segment of his Thursday night show, “The O’Reilly Factor”, flagged by the advocacy group Media Matters. “If you make the behavior of these people ... if children hear it, unsupervised children, okay who don't have parents watching their — they might go out and experiment with this stuff.”

I'm pretty sure that when Bill O'Reilly was a kid, and he "experimented" with being an asshole, that didn't make him become one. It's a pretty fair guess that he was born that way.
