It’s highly unfair to charachterise all Chrisitans as holding that idiotic, creationist view point.
However, given the extremist positioning that the Vatican, and many American ‘born-again’ churches have taken on this (and many other) topic, the generalisation of this comic-meme seems to be fast becoming almost true.
In fact, my big fear is that we may soon see a Christian equivalent of the Islamist extremism we see in Asia & Africa – unless one conform to the extremest possible interpretation of the religious beliefs, one’s deemed to be a non-believer.
What’s worse is that last time these two religions staggered their dive into orthodoxy, to the benefit of (almost) all humanity. While Christian Europe was wallowing in ‘dark’ middle ages, Islamic societies were flourishing in scientific and artistic achievements. When Islamic societies stumbled, Christian lands took over the charge, undergoing a renaissance, to be followed later by an industrial revolution. Between them they kept scientific and artistic growth flourishing. (Not discounting the numerous contributions of non-Abrahamic societies in China, India, and elsewhere.)
What a shame it is, now, to see the leading societies (nations) of both religions race each other to the bottom of orthodoxy.
