If Christianity were only stupid and unscientific, if its God was ignorant and kind, if it promised eternal joy to believers and if the believers practiced the kind of forgiveness they teach, I, for one, should let the faith alone … But there is another side to Christianity. It is not only stupid, but malicious. It is not only unscientific, but it is heartless. Its god is not only ignorant, but infinitely cruel. It not only promises the faithful an eternal reward, but declares that nearly all the children of men, imprisoned in the dungeons of God, will suffer eternal pain. This is the savagery of Christianity.
— Robert G. Ingersoll
