Thanks for the question. In my opinion, Bill O' Reilly is very passionate about his political views, and there's nothing wrong with that. Well, you've heard it, he's told people to shut up multiple times, and that's his problem. He shuts people down because he has no arguments that support his political views. On a recent live interview on National Public Radio, when he was confronted with factual arguments that were against him, O' Reilly simply stormed out of the studio. The bottom line : Bill O' Reilly has no supporting arguments for his political view, but that doesn't mean that there aren't any.
I hope this will help you.
P.S. Don't take my words and use them for your homework.
