Recent situations like the hijack of an airplane in Mexico city and the killed people in the Balderas subway station and remembering tragedies like the past on New York, Madrid and London, as well as many historic episodes like crusades, witch hunt, inquisition, many wars, etc… remind me a phrase I first heard in the the documentary The root of all evil? (the foundation of The God Delusion):
Religion is an insult to human dignity. With or without it, you’d have good people doing good things and evil people doing evil things. But for good people to do evil things, it takes religion.
