A blog called Ex Nihilo circles around the "intelligent" "design" vs. evolution issue that really lurks in the back of the conservatives' minds: the ol' Nieztchean Thus Spake Zarathustra stuff about the death of god.
The idea that there can be a morality, and an ethic based on what we know and don't know, where we are, seems to evade these folks.
And the subtext is clear: if there's no i.d., then they should not believe...
But also buttressing that belief, it seems is the belief that with them personally and with society as a whole all hell will break loose if their religious construction proves to be faulty.
I would humbly suggest to them that they try harder.
