I think the issue may be more closely related to fundamentalism and fanticism than faith. History is resplendent with examples of horrific acts committed by both the religious and non-religious.
IMHO, the problem is one of extreme behaviour of an exclusionary nature, regardless of origin.
The mindset of faith, especially faith in invisible deities and rewards in the afterlife, is not conducive to critical thinking or responsible discourse.
I think you would have a hard time supporting such an assertion. While there might well be differences between two people who discuss faith or religion, I don't think you can arbitrarily say that those with faith are less able to think critically than those without.
I assert that a person's faith is indeed relevant to his ability or willingness to treat people with tolerance and goodwill, and certainly affects the importance he places on empirical evidence.
Well, that can certainly be read both ways. I, for one, would agree that those with faith would be more likely "to treat people with tolerance and goodwill". The issue is that there can be bigots across the spectrum, believers and non-believers. On the bell curve, those that fall in the extremes regardless of faith are more likely to show less tolerance than the vast majority.
