I see it this way:

We are hard-wired for the MOTIVES (which are provided by our evolution) but have a choice, provided by our intelligence, when it comes to whether to exhibit the BEHAVIORS thus motivated, or other behaviors, or none. And it is the degree to which we exercise those choices that determines the degree to which we are civilized.

And *that* is my main argument against the fundies - that they voluntarily, seemingly, abandon that very capacity for evaluating and deciding, by choosing dogma over reason. It's dehumanizing, and that's what makes it so wrong to me. It's as if they have to revert to some atavism in order to deny evolution, and they thus make it true that they, at least, are refusing to evolve with the rest of humanity.

Because our current knowledge of the biologies is astounding, and we can bring all that knowledge to bear on a lot of important decisions that fall under the category of Should we act upon our urges.
