Christian doctors should have to identify themselves as such so patients understand that at some point they throw out logic, reasoning, and the scientific method. People who travel the world to push books and "spread the word" have no place being in any position where they may try to push, influence, or alter care for another. They need to be identified and monitored closely otherwise as they cannot be trusted. People who toss out logic, reasoning, and the scientific method have no place caring for the public.
