Yes Bill O'Reily's television program has a lot more opinion then it does fact. That is why he is on the air though. O'Reily brings to topic many issues he feels strongly about and while basis them on fact also gives a large opinion into them as well. It is the format of the show.
Yes, Bill O'Reilly's television show contains more opinion than fact, because that is the purpose of his show. He gives a brief overview of the news and then he comments on it. He even has sections where he states his opinion. He calls the show a "No Spin Zone," but really what he does is spin the news in his perspective.
I believe Bill O'Reilly's television show does contain more opinions than facts. It has become widely known that both Fox News and CNN are terribly biased. It's easy to see this simply by going back and forth between the two channels. Bill O'Reilly's show in particular is more of a discussion forum in which his opinions are aired and/or those of the Republican party.
Bill O'Reilly's television shows and books are intended to be taken as political commentary rather than political news. He mentions some facts, but his intention is to persuade people to believe his opinions. Although he is featured on a new channel, he has always been more of a commentator than a real reporter.
Bill O'Reilly's television show does contain more opinion than fact. He does know how to make the news interesting. I think he over does it sometime with his own opinions then the facts. He is interesting to watch and get his own view on something that is currently in the media.
