Not to single the Christians out too particularly, mind; Muslims were praying for Allah to keep the rain of Cyclone Sidr off Bangladesh just as hard, with no doubt even greater urgency but to equally little effect. There’s a significant CHristian minority there too, of course.
As a commenter on Pharyngula pointed out, the call for prayer went out after the forecasters, using their heathenish science, had already predicted some light showers – not enough to significantly affect the drought conditions, mind, but no doubt enough to let the ignorant fools think that their wishful thinking had had an effect.
Too bad about Bangladesh, though. Obviously God chose to test them, rather than hear their pleas. He’s a funny old bugger that way, God is. Unpredictable. Except maybe by heathenish scientists, and they only predict and encourage preparation; they can’t affect the outcome, because they aren’t the chosen ones of Big Sky Daddy.
(when, oh when, is the rest of the human race going to grow up and face reality?)
