Sidenote: In the paperback preface of the God Delusion, Dawkns addressed the criticism that:
"You ignore the best of religion and instead . . . “you attack crude, rabble-rousing chancers like Ted Haggard, Jerry Falwell and Pat Robertson, rather than facing up to sophisticated theologians like Bonhoeffer or the Archbishop of Canterbury.”
His reply was, "If subtle, nuanced religion predominated, the world would be a better place and I would have written a different book."
Here is his reading of the preface and explaining that argument:
