I would only take issue with Casey's comment about Christian apologists. I think that it's an overly generalized statement. Christian apologetics is a very large community. You can find some very open-minded and educated people among them, people who will gladly interact with non-conservative views. But you can also find the sort of people that he describes. I also find it interesting that Jesus mythicism is promoted almost exclusively among former fundamentalist Christians in America, people who have taken the exit route and now treat all gospel claims as pure fabrication.
