Through all the ages of superstition, each nation has insisted that it was the peculiar care of the true God, and that it alone had the true religion — that the gods of other nations were false and fraudulent, and that other religions were wicked, ignorant and absurd. In this way the seeds of hatred had been sown, and in this way have been kindled the flames of war. Men have had no sympathy with those of a different complexion, with those who knelt at other altars and expressed their thoughts in other words — and even a difference in garments placed them beyond the sympathy of others. Every peculiarity was the food of prejudice and the excuse for hatred.
Robert Green Ingersoll – “God in the Constitution”
