O'Reilly constantly calls people who see gay sex as sinful as religous fanatics and extremists and has no repect for their beliefs in the Bible. O'Reilly is entitled to his beliefs, but his constant name-calling of those he disagrees with is bigotry.
If O'Reilly has a belief that people who see gay sex is sinful are religious fanatics (a lesser accusation that saying you are a sinner), does that make him an anti-Christian bigot?
