I don't have answers for myself, so i'm not going to pretend to have answers for 50% of the world population. I'm certainly not going to assess their beliefs on the basis that what I might believe is somehow more correct than what anyone else believes.
Intelectual or theological superiority combined with moral authority is what leads to intolerance and hate. I'd rather somebody believe in the easter bunny or pray to Kim Kardashian 5 times a day and be tolerant of others than be closer to my own agnostic view and attempt force it on others because they are more correct.
