Best quote I've seen was in a story about climate change, but it's relevant here as well:
"People ask me if I believe in global warming. I tell them, 'No, I don't,' because belief is faith; faith is the evidence of things not seen," Hayhoe said. "Science is evidence of things seen. To have an open mind, we have to use the brains that God gave us to look at the science," she said.
There is no one who does not "believe" in evolution. It's not a matter of "belief". There are people who do not understand evolution, and thus claim they don't "believe" in it, and there are people who do understand it and lie about believing in it.(Sometimes, they're lying mostly to themselves, but most of them prefer to lie to others. It pays better.) If you understand evolution, not "believing" in it is like not "believing" in gravity.
Of course, to be fair, we could argue such people should be denied access to any kind of technology which directly or indirectly springs from evolutionary theory. For example, without evolution, bacteria could not develop resistance to antibiotics, so they should not be given newer antibiotics which overcome those evolved resistances. Since no new species of life can ever appear, they should not have any treatment against new iterations of old diseases, such as each year's exciting new flu, or diseases which were not known at all until recently, such as AIDS.
Nor should they have access to virtually all the food crops and animals we use... selective breeding, even as practiced by the earliest peoples, only works because evolution is true. Evolution, in its most basic form, is, to quote Wikipedia, "change over time in the inheritable characteristics of biological populations". If you can breed cattle or wheat so that, over time, some variants vanish and other variants appear and dominate, you have changed the inheritable characteristics of a biological population.
If you do not believe in that, there are virtually no domesticated plants or animals that you should eat, because they can't exist -- we should see the same kind of crops now as the earliest humans planted, with the degree of variation within them completely unchanged.
Please don't say "But that's not the same thing as dinosaurs turning into birds!", or any similar twaddle, because it IS... if you understand evolution. If you reply with any kind of variation on "But that's not evolution!" or "That's not what I'm talking about when I say I don't believe in evolution!".. you're in the group of people that don't understand evolution.
