 Liddle begins the documentary by attempting to survey common criticisms of religion, and particularly antireligious arguments based on the prevalence of religious violence.He argues that the "very stupid human craving for certainty and justification", not religion, is to blame for this violence, and that atheism is becoming just as dogmatic as religion.In order to support his thesis, Liddle presents numerous examples of actions and words by atheists which he argues are direct parallels of religious attitudes.
