After years of debate on here (and elsewhere, both online and in person) with religious fundamentalists, there's only one conclusion that can be reached.
Their brains are switched off!
Im not talking about the average person who happens to have a religious belief. I mean the fundies. Those who believe whole heartedly in a given dogma and wont make any concession that they may be wrong, despite been shown evidence to the contrary.
I remember reading an Arthur C Clarke article once where he talked about a team of scientists who set up an observatory in a muslim country to observe a solar eclipse. The team of scientists were ridiculed by the local clerics who said that only Allah knows the timing of such things. After the eclipse, the clerics accepted that it had happened but said that it was nothing more than an amazing coincidence...
I have no problem at all with religious believers, but some (like the clerics above) cant accept the bloody obvious even when its been presented to them right before their eyes.
It gets passed over like its never even been read!!!
