That's absolutely not true. Do you somehow not realize that the process that evolution describes takes millions of years to work? There is no possible way that disbelieving evolution can effect the effectiveness as a doctor.
That's like saying you can't develop a PHP app unless you understand Turing theory. The bulk of the internet proves such an assertion wrong.
And good luck with those Turing-denying programmers you hired. Let us know how they work out in the long run. There's a difference between someone who doesn't completely understand a given theory but accepts the process that led to it, and someone who actively denies the theory and, in doing so, rejects the entire epistemological framework it rests on.
I'm still waiting for you to give a concrete example where not knowing or believing evolution will cause a doctor to make a wrong choice. At is typical, people like yourself rely on hand wavy "you just don't understand" nonsense.

What I'm telling you is that most of the PHP sites on the web are made by people with little or no understanding of the fundamentals of the technology they use. And they make a living just fine. Honestly, I suspect Zuckerberg would be in this group as well. Fundamental understanding is never required to get results, no matter how much we may wish it so.
Obviously I do, since I'm the one who said it.
Do I care if my car mechanic believes in ghosts?
Do you care if your electrician believes in Ohm's Law? Because that's what it means to deny evolution, for anyone whose job is even remotely connected to biological science. Your car mechanic analogy is irrelevant, because car mechanics don't confront decisions in their professional life that may bring them into conflict with their religion.
A better way to phrase your question might be, "Do you care if your car mechanic believes in phlogiston?" That would be "Yes."
