Sandy has a point. As atheists, we have often pointed the finger at atrocities carried out in the name of religion -mass murder, massacre, rape, pillage, ethnic cleansing and more.
This sentiment is often countered by those of a religious persuasion highlighting the regimes of Stalin, and Pol Pot, alleging an atheist basis for the massacres.I think the reasons for such persecution and massacre within the Bolshevik revolution and PolPots reign of terror in Cambodia were not as simple as repression of religion alone,but it played a part.
We cannot claim that mans inhumanity to man is entirely the preserve of the faithful - only that the schisms between religions provides a more fertile ground for such behaviour, a wider catchment area, and an easy get out clause ("I will defend my god" / "God told me to do it").
We can also point out the hypocricy of such violence and morally repugnant acts on the part of the believers - it is they who claim a higher moral standpoint, who claim a greater spiritual awareness of the universe - and whose followers all claim to follow a god that promotes love, harmony and peace amongst men.Any religion that does not categorically condemn the practice of using suicide bombers, or inciting death through fatwa, or bombing of civilian areas in order to kill some "terrorists" or that do not categorically condemn the random killings by an individual claiming membership of the knights templar stands exposed as morally bankrupt.
