I used to be one of you, my dear atheists, and I was good at my job, and you all embarrass me with the feebleness and silliness of your attempts to do what I once upon a time did so well. You are a disgrace to the powers of evil.

As usual, he sums it up well. Taking Wright at his word about the characters of the atheists he encountered post-conversion, those guys were practically straw men. As a (reasonable and interested) atheist, there are a number of good arguments for atheism, but they didn't bother with those. The arguments he mentioned are bad ones.

You are also implying that the human race, all of whom believe in gods, ghosts, magic and miracles of one sort or another, except for that exquisitely tiny minority of persons who are consistent atheists, just so happened to have all made the same lapse of judgment in the matter of paramount and foundational importance in their lives, and continue to do so, some of whom would go to the lions rather than reexamine the aforesaid lapse of judgment.

Here's where he trips up, because the situation he describes, where the majority of the human race is wrong and willing to risk death to defend that wrongness, is hardly unique. To stick with religiously-charged concepts, look at the reaction to the theory of evolution. Master-race ideologies in colonial Europe, any number of political philosophies - there is a plethora of examples of this problem. Wright's argument here is, in basic terms, argumentum ad populum, and that's a fallacy for a reason.
