Faith is also divisive; when coupled with insecurity, dogma and much bullheadedness, faith blinds and stops the ears; I've not seen any amount of faith directly violate physics. It failed its acid test, for me, when it did not bring back the woman I loved.
There is still a place for faith. Humanity could not have done much anything without it. Humanity needs faith. But people can't be blamed overmuch if they set it aside for a more reliable method of epistemology.
Personally, I still have faith in humanity. I still believe that we can guide ourselves out of the morass of its myriad problems-- whether that happens because of a God's guidance, our innate nobility or sheer dumb luck, I care not. I believe we can, because I must. Mankind, for all its faults, is too precious to allow itself to lay down and die.
