>So, what do you call me the thing that drives otherwise reasonable humans to hate each other?
Go to Google News and search for the terms 'sectarian violence', 'religious violence' and 'blasphemy'.
There are the Sunni and Shia killing each other in the Middle East, the Christians and Muslims killing each other in Nigeria and Hindu religious leaders calling for the mass killing of Muslims in India. In Pakistan, angry mobs regularly beat people to death and set them on fire for the merest perceived slight against Islam.
There is far too much intolerance, violence, misery and death in the world today caused by people acting on or motivated by their unsubstantiated religious beliefs.
