Those "Christians" you describe are often nominal. Saying you are fed up with those people is like lashing out at pancakes because those people say they love pancakes, too, or refusing to drive cars because they drive cars as well.
The only reason "American 'Fox News' Christians" are any significant number of the population is because Christianity as a whole (and unfortunately there are a lot of denominations who don't profess Jesus as God which are lumped into Christianity, but I digress) is a major religion, and historically
the major religion in the United States, where religious freedom has made it easy to be (or, rather, claim to be) a Christian. It's a result of Western civilization being a major power and bringing Christianity and the culture of it along with it.
If you had met any of the Christians from countries where persecution is a reality, like in India or Pakistan, or in many Middle Eastern nations, you would get a real and better understanding of who Christians are. It was very hard for a long time in the communist countries like Russia and China for many decades as well, and it's still very dangerous in North Korea to be a Christian. Visit Voice of the Martyrs
website if you want real examples.
Not to say there aren't any real Christians in the United States, but its persecution that separates the wheat from the chaff. Not that hard times are a very desirable thing, but its hard to embrace truth when materialism forces it out of the way.
I'm a Christian, and while you might disagree with a lot of what I believe or even think my beliefs ridiculous, you would have a hard time pigeonholing me with your description, and in fact many of my friends and fellow Christians don't fit your view. I hate Fox News (and CNN) and mainly watch Al Jazeera and Euro News, and mostly just read Reuters and other sources online. I don't fear or detest people of other religions or races, and in fact I have and have had friends from just about every ethnicity and religion you can name, as well as atheist and agnostic friends.
As for the topic of this thread, it's just another guy looking for attention in order to sell books. There's a reason he's building up attention and interest beforehand and pointing to his website and book, and I doubt it's purely just academic. Regardless, even if he has some genuine source, just because a document is old or dates back to that early church period doesn't mean it wasn't a fabrication of the time. Plenty of the gnostic "sources" were later disprove as just attacks on Christianity. The same kinds of material can be found today, and since Christianity has been around for nearly 2,000 years, of course you'll find many centuries of people writing diatribes and false claims about the Bible. If someone quoted an AnandTech conspiracy thread somehow still in existence 2,000 years from now, those future people shouldn't be quick to believe the OP of it.
