Or blaming the holocaust on biologists who accept and work with the theory of evolution. That's the point of the "Hitler was a Darwinist" claptrap, isn't it?
I myself don't try to discredit Darwin by blaming him for Hitler (mach shemo!) because the whole point of my argument is that in the absence of G-d there is nothing objectively morally wrong with genocide or selective breeding or hatred or mass murder or anything else. People who try to appeal to the non-theistically-based moral hang-ups of atheists are merely reinforcing the idea that some things are "obviously wrong" and "we don't need G-d" to tell us so.
Ain't I a consistent little thang???
