Here and here, historian of Nazi Germany Richard Weikart responds to yet another whitewash of Darwinism's role in helping to create a particularly malignant type of racism, this time by Darwinist Michael Ruse:
Last November at a conference on Darwinism I conversed with a graduate student in philosophy who embraced Ruse's position on the evolution of ethics, which is not all that unusual among evolutionists. He told me he believed that morality is a biologically innate response shaped by evolutionary processes. It has no independent, objective, or universal existence.
I pressed this graduate student, asking him how far he was willing to take his ethical relativism. Upon his affirmation that he subscribed to it completely, I asked him if he thought Hitler was morally evil. After explaining that he personally found Hitler's views repugnant, he admitted that he had no basis for condemning Hitler and finally he conceded, "Hitler was OK." I doubt Ruse would be comfortable saying that Hitler was OK, because Ruse's (and Darwin's) political views are miles apart from Hitler's. However, Ruse's worldview (and Darwin's own) does not, as far as I can see, provide any objective basis for opposing or condemning Hitler (or Stalin or Mao).
Weikart is repeatedly accused of saying things he does not say, principally, one suspects because the things he does say and can demonstrate are so damning that the only alternatives are acknowledgement or obfuscation.
Here's an interview I did with Weikart on how he got interested in Darwin and Hitler anyway (not how you might think).
