As an atheist, I am constantly appalled by the religious systems that keep their followers in the dark, denying reason and facts, and creating horrors in the name of some god.  Recently a friend of mine suggested that it may be futile to fight against these systems or even to be upset by it because, "things are the way they are because of 'human nature', not because of religion. Religions are the symptom, not the cause..." If it wasn't religions it would be something else that divides us.  This seems a very bleak view of ourselves.  What do you think?
