With respect, I don't think that is an accurate characterisation of 'evolutionists.' Darwin himself is as good an example as any: born on precisely the same day as Abraham Lincoln, he grew up in Shropshire (a beautful part of the world, btw) and developed a keen interest in the natural world, and considered for a time entering the priesthood. As ship's naturalist aboard the Beagle for nearly five years, he made careful observations and measurements of many natural phenomena (biological and geological)--throughout this time, he professed a basic Christian belief. He spent two decades evaluating the evidence he had gathered, from which he assembled the (incomplete) theory published in 'Origin of Species.' He was reluctant to publish for fear of the inevitable challenge TOE presents a literal reading of Genesis, and the possible upset to his wife Emma, who was particularly devout.
It is true that Darwin 'lost' his Christian faith, though probably as much through the emotional crisis of the death of his daughter as anything else, but it is simply wrong to claim that Darwin, or indeed any of the multitude of serious scientists who have built on his work and insights, have set out with an agenda to banish God (or Allah or the Flying Spaghetti Monster) from the universe. Evolutionists do not have a religious agenda.
But it is the case--and I think some of the postings in this thread demonstrate the fact--that proponents of Creationism/ID (and let's be honest, they come to the same thing) are pursuing a specific religious agenda, and in the inappropriate venue of the science classroom. I am as alarmed by that as I would be if an Iranian ayatollah were put in charge of the science curriculum, and I think you would be too!
