I agree, "afraid" was a poor choice of words. Bygones. How about "Why do those with a belief in God find the theory incompatible with that belief?"
Well, then, that's a whole new universe. I, for one, don't. And I personally know no Christians who see any incompatibility.
Well, insofar as people do, it's mostly a backlash against evolutionists who have used Darwinism to attack Christians for the last century. Heck, even here on FR you can find vestiges of that.
But here's my thing: Since I believe in a God who can create by fiat but who may choose to exercise His power as He wills, Darwinism (that is, strictly as a scientific theory) isn't a problem for my faith in Jesus Christ--but I'm not married to the theory the way some people are either. I can therefore look at it skeptically and demand that those scientists promoting it prove it rather than assume it without undermining my worldview. A non-theist (and I'll include Deists in that category for this discussion) tends to assume the truth of evolution and accept its claims by faith, having no other "creation myth" to fall back on.
I'm principally a proponent of Intellegent Design, which as a theory is not contrary to the theory of evolution itself (in fact, many IDers are also evolutionists). However, I get greatly annoyed by the presumption of many of the evos here and elsewhere that, "Well, evolution is so manifestly correct that anyone who challenges it must be an idiot, a charlatan, a fundie, or all three at once!"
I can't help but notice the parallelism between that kind of attack and the rantings coming out of the blue counties about the rest of the country right now.
Quite aside from abiogenesis, which is such an absurdedly insoluable problem for abiogenesis that many of the best evo proponents try to simply avoid the subject, claiming that it has nothing to do with the core of Darwinism, there are other problems with the evidence for the theory insofar as the fossil record and such are concerned. These problems are pretty much expunged or glossed over in textbooks, while manifest frauds are still taught as evidences. I have a real problem with that.
In any case, the fact is that despite billions of dollars of both government and private funding and well over a century of having a lock on the educational institutions and media, and all the fraudulent "evidences" (Nebraska man, the peppered moth photos, etc.), fewer people firmly believe in evolution than believe in the Virgin Birth. Perhaps if the evos stopped acting like a bunch of Michael Moore democrats scalded by the election results, they would take the time to find out exactly why that's the case. Go read some of the literature on our side, guys: It's not ignorance of the facts, its another perspective on what those facts add up to.
