I don't want to be treated by a doctor whose religious beliefs, no matter what they are, are so much more powerful than their ability to reason that they walk out of a an evolution lecture. These are people who are entering an evidence based discipline, and a bigot (yes, I use the word correctly) has no place in such a field.
I don't think it's unreasonable to ask your doctor their thoughts on evolution, refusing their services and branding them 'mental pigmies' based on their response, irrespective of their religious beliefs or lack thereof.
But then, I don't live in the US nor the middle east, so I can afford to do that.
