"So only atheists are in a comfortable position to cast the first stone, and Christopher Hitchens, in "God Is Not Great," relishes the role. He has the credentials, as both a combative journalist and a surprisingly erudite literary scholar, and he wants to break the diplomacy barrier and expose the preposterous presumptions and ignoble machinations that stain the history of all religions, bringing discredit that tends to get magnified over the years by a persistent pattern of coverup, veils of illusion, and denial of one design or another. These efforts at obfuscation are quite transparent under Hitchens' s merciless scrutiny, and the results are often quite comical."
