It's difficult for people who live in a culture where there is only one "right" way taught to them at home and in school to open their minds to alternative possibilities. I always ask devout Christians, or Muslims, to consider their position if they had been born in another place and into another culture. Surely then they would have as much conviction about a belief they now totally reject. No one faith can simply be right, and all the others wrong. For myself I try to see all faiths from a historical perspective, try to understand how they emerged and why. If they give people who have very little the hope of a better life after death then that hope is a worthwhile thing in itself. I have no problem with any faith which gives people a code to live by which is kind and loving, provided they don't claim exclusivity and proclaim a right to convert everyone else.
