There is indeed "a clear case" for belief in evolution. In fact, the case is so clear that I would not want to put my life into the hands of someone who knew the case but rejected it, because there's no telling what other well-founded knowledge they might reject out of hand because it doesn't fit their preferred beliefs, or what practices they might follow as a result of it (e.g., Christian Scientists who reject the process of life-saving blood transfusions).
I would no more want a physician who rejected evolution for fundamentalist grounds than a physician who rejected other parts of modern medicine out of a belief that acupuncture and its effects on the "chi" flow of the body was the "real" root cause of health and disease.
Many competant physicians are not evolutionists.
I require more than mere "competence", thank you very much.
And frankly, from the anti-evolutionists I've met through the years and had long discussions with, I can't say that I have much confidence that most of them could even rise to the level of "competent" when it comes to complex technical issues. I sure as hell wouldn't want any of them doing surgery on me.
