I warn you that 1) I can't speak for Hitchens, Dawkins, et al, and 2) exploring a non-religious viewpoint requires a degree of broadmindedness that some religious people seem to find quite uncomfortable.
It's an amazing straw man you set up there. You must be so, well......broadminded......
*rolls eyes*
No, it doesn't. Atheists are usually small- and simple-minded. Following logic is the easiest thing an engaged brain can do.
It requires far more "broadmindedness" to consider and accept the existence of that which can't be physically sensed.
