That was simply unprofessional behavior by the Fox anchor. Fox News needs to revamp their whole organization. Their motto of "Fair and Balanced" is insulting to viewers intelligent enough to see the blatant and regular spin they put on news.
The irony is that Fox's practice of spinning news towards the far right might actually be bad for the Republican Party and their desire to win national elections. Fox undoubtedly has enormous persuasive powers over a certain segment of the electorate. I personally know several people that essentially get no other news about the world other than what they procure from watching Fox News on a regular basis. When your party becomes filled with extremists it alienates moderates and independents. However, Fox's descent into what can only be likened to "tabloid journalism" and borderline political propaganda might actually be good for their business model. Turning news into infotainment increases viewers. Viewers who would likely be otherwise bored at a straight reading of the news of the day. Delivering the news with political spin equates to increased revenue for Fox from advertisers.
Fox News is also capitalizing on the Republican Party losing national elections. Now bear with me, but having the Democratic Party in control of the Executive Branch allows Fox to perpetuate their particular brand of "outrage news" which keeps many tuning in. If Governor Romney had won the last election, Fox would have less to protest about, i.e., they would lose viewers. It makes good business since for Fox to play to and increase the partisanship of their viewers. Fortunately many Republican politicians are realizing that going further and further right is a poor, shortsighted strategy to appealing to a majority of voters.
Violia, I would agree with you that MSNBC is a very biased organization with a clear agenda. Nonetheless, that doesn't excuse Fox News from having to hold themselves to certain journalistic standards. I can't truly justify my poor behavior by finding someone else committing what I feel is worse behavior to point fingers at. If Fox wants to be taken serious as a news organization they need to hold themselves to a higher standard, not point fingers at extremists on the left (MSNBC) and cry, "Look, they're spinning the news too!"
It looks like this interview has brought the author great advertising for his book. Albeit at the expense of Fox's credibility.
The anchor's argument had one giant, glaring flaw. The premise of her critique was that as a non-Christian the author would be unable to give an accurate, unbiased account of Christianity or Jesus of Nazareth. However, by that logic the majority of Fox broadcasters should be unable to give an opinion of Obama or any other news issues pertaining to the Democratic Party. As obvious Republicans, they would be unable to give accurate information concerning Obama or his policies. You can quickly see how faulty the host's reasoning is.
