Almost all religions provide opportunities for human beings to convince themselves of their own righteousness, to speak in the name of God, and even to go to war on God's behalf. This 'blasphemy of certainty' is also rife among secularists who in their case have not God but science or the proletariat on their side.
Pretending that the world’s religions are the same does not make our world safer. Like all forms of ignorance, it makes our world more dangerous. What we need on this furiously religious planet is a realistic view of where religious rivals clash and where they can cooperate.
