About a year ago he did an anti-fundi story and an anti-homeschool story in the same week. Haven't seen him since but that's when he jumped in my opinion.
When O'Reilly, in an interview about homosexuality, referred to something from the Old Testament by saying, "Well, it's not gospel." He was not speaking in Biblical terms. He was using the phrase in the slang sense; he simply meant that what he was referring to from the Old Testamant wasn't necessarily the undisputable truth.
