I think it's safe to argue that most people, even atheists and/or scientists, demonstrate a
faithful devotion to an acknowledged ultimate reality, and are therefore religious. While I can understand the argument of science vs scripture, I'd argue that both sides of the debate are equally religious in terms of their own beliefs; therefore, pointing fingers at "religious people" is a tad absurd.
