It's an excellent quote and it does explain the biggest problem with having the atheist stance. Sometimes office politics turn to religion and working with mostly muslims, their thoughts on religion are very all or nothing, not the unsure thoughts of the average Christian in the UK. I tend to keep quiet and just nod, I gave up on religious debate mainly because of this very issue! What's the point in arguing what can't be proved or disproved... The phrase "pissing into the wind" comes to mind.

But then again, I don't disagree with having faith as long as it's harmless. I think the percentage of people with harmless faith is much greater than those who might be dangerously obsessed. We just need to wait for it to break even, time is the only cure. From my experience the more you tell someone not to do something, the more likely they are to do it. Save your breath!
