Re: An important idea here.
The most fascinating, and potentially instructive, aspect of human nature would be the entire process of how and why he was appointed to the House Science, Space and Technology Committee.
You also raise an interesting point of how someone who _appears_ to reject modern scientific belief (in certain areas) can practice as a physician. It is probably the case that you don't need to deeply understand medications to know which ones should be prescribed for certain ailments. I don't need to believe in evolution to believe that antibiotics cure many bacterial infections and he doesn't need to 'believe in science' to know which antibiotics are best and what the side-effects and potential interactions are. Any belief that the world is 9,000 years old has no bearing on his ability to set a broken bone and give advice about diet, .... etc.
It is possible for a person to have a high level of functionality in modern society while rejecting many modern scientific beliefs, but the problem, for other people, is when that person is in a position of great influence in those areas that depend on modern scientific beliefs.
