If you really look at the motivations of contemporary atheists, you'll find that they don't even really reject Christian theology. It's not as if the atheist objects to the resurrection or the parting of the sea; rather, it is Christian morality to which atheists object, particularly Christian moral prohibitions in the area of sex. The atheist looks at all of Christianity's "thou shalt nots" -- homosexuality is bad; divorce is bad; adultery is bad; premarital sex is bad -- and then looks at his own life and says, "If these things are really bad, then I'm a bad guy. But I'm not a bad guy; I'm a great guy. I must thus reinterpret or (preferably) abolish all of these accusatory teachings that are putting me in a bad light."
I'm pretty certain atheists reject the resurrection of Christ and the parting of the Red Sea, and I'm pretty certain Christians consider moral prohibitions part of their theology.
I have no doubt in my mind that Marcia Segelstein -- who claims that D'Souza writes "with cocksure prose that only a thinker at the top of his game could muster" -- is a complete fucking moron.
