"Religious fanaticism has clearly produced, and in all probability will
continue to produce, enormous amounts of bickering, fighting, violence,
bloodshed, homicide, feuds, wars, and genocide. For all its peace-inviting
potential, therefore, arrant (not to mention arrogant) religiosity has
led to immense individual and social harm by fomenting an incredible
amount of anti-human anti-humane aggression."
