I agree that the case is overstated, DB, but I can't help but think that the author has a point about a sudden decline in 0ld-style Christian evangelism. The problem, as I see it, is that the internet has irretrievably changed the way we get our information. Anyone who has the slightest interest now can meet with and debate the most passionate defenders of atheism, not to mention other philosophical and religious points of view. All the arguments are out there and exposed now. That is a radical change from the 50s and 60s, when the public perception of atheism was limited to figures such as Einstein (not an overt atheist, but debating Bishop Sheen, the first televangelist) and Madlyn Murray O'Hair.
I do not think that the association of evangelists with the failed conservative movement is quite the blow that the author does, but it is symptomatic of the problem. Evangelical Christianity needs to reposition itself in order to survive. The younger generation is just not receptive to the old way of thinking. I suppose that sntjohnny agrees with this to some degree, although for different reasons. He sees the boat as capsized, but he feels that he has a recipe for setting it right. In any case, we can probably all agree that religious conservatism and fundamentalism faces a big problem in the US in the near future. Politically, they are in decline for now.
