"The experts aren't experts, and so they've passed their non-expertise onto the masses, and it isn't just the Church. Beck is doing the same thing in the political realm. One of the absolutely legitimate points I took from Rapture Ready is that anything banal, crass, or pitiful in Christian culture has a reflection or is a reflection of the same reality in non-Christian culture. I guess that means it's a reflection of the human tendency toward the simplistic, crass, over-generalized, and banal. Make it simple. They'll buy it, even salvation."
I have noticed this tendency among the right to anoint "experts" who's only expertise is that they support the conventional wisdom of the right. Engineers who oppose evolution become scholarly experts--even though their expertise has nothing to do with biology. In the same post, Greg notes an article he penned on this movement and he connects this expertise issue to the faux historian David Barton. (You might even recognize the historian Greg contacted to refute Barton.) Barton has no training as a historian, yet has become someone who Mike Huckabee referred to as America's best historian. Please.
But the point is that this fake expertise gives many on the right a plausible (to them) source to confirm their beliefs. I know they believe that the left does the same thing, and that is sometimes true. But in history, it is not. And those of us who actually work in or around the field know it. We know how much historical conclusions are challenged and battled. We know the process of getting something published through peer review. We know the examination on sources and skepticism to new interpretations. Those processes are, as Greg noted, completely gone in a world that has gone to the simple.
