Why were the Nazis so disagreeable?  Because they were force-fed evolution, of course!  Christian podcaster Greg Kokul thinks he’s uncovered the Nazi/evolution connection.
In a recent Stand to Reason podcast (starting at 5:00), Kokul spoke of being informed that German soldiers during World War II were issued two books, Goethe’s Faust and a German translation of The Origin of Species.  And it was Hitler himself who insisted that they get them.
(Wow—right out of the gate we’re embracing Godwin’s Law!)
About the logic behind Hitler’s assigning these books, Kokul says:

It’s because the ideas in The Origin of Species served [Hitler’s] purposes well, and if a person actually believed what Darwin taught, then they would make good Nazis.

My first complaint is that Kokul accepted the story uncritically.  This story nicely supports his worldview that evolution is both harmful and wrong, so he passes it on with no fact checking.  I do my best to take the opposite approach: when I find a delicious story that skewers an opponent (either a person or idea), I want to make sure that I have strong evidence so that I don’t look ridiculous after passing on flawed hearsay.
In doing my own research on books issued to German soldiers, the only page I came across was a post in another atheist blog (IAmAnAtheist) who’d heard the podcast and asked the very same question.  That blogger raised a great point: Why issue those two books and not Hitler’s own Mein Kampf?
That Origin was a central part of Nazi thinking seems unlikely.  The official Nazi library journal in 1935 listed twelve categories of banned books.  One category was:

Writings of a philosophical and social nature whose content deals with the false scientific enlightenment of primitive Darwinism and Monism.

(If anyone comes across evidence for this books question either way, please add that to the comments.)
Now let’s move on to critique Kokul’s ill-informed ramblings on evolution.  One of Kokul’s favorite ploys is to try to tie eugenics with evolution.
First off, Darwin himself rejected eugenics.  In The Descent of Man, he said, “No one who has attended to the breeding of domestic animals will doubt that [not culling the inferiors] must be highly injurious to the race of man.”  Creationists enjoy quoting just the paragraph that contains this sentence and ignoring the very … next … paragraph where he overturns this argument.
Darwin rejected eugenics, Greg.  Of course, you’ll be quick to backpedal and argue that Darwin’s own personal opinions say nothing about the validity of evolution.  Agreed!  Which is why whether or not Hitler kept his copy of Origin under his pillow says nothing about the central issue here: Is evolution the best explanation of why life is the way it is?  Which is why this entire conversation is simply mudslinging.
“Hitler was bad, and Hitler and Darwin were BFFs!  And Darwin was ugly!  And … and he probably ate babies!  And didn’t recycle!”  Whether true or not, it’s irrelevant.
This is what one does when one doesn’t actually have a real argument.
Science is not policy.  Evolution is science (the domain of scientists), and eugenics is policy (the domain of politicians).  Any scientist who advocates eugenics has left the domain of science and jumped into policy.  Eugenics isn’t science, and criticism of eugenics is no criticism of science.
Which brings up the last point: Did Hitler base his eugenics policies on evolution?  Kokul seems to imagine a kind and gentle Adolf Hitler, picking up litter and helping little old ladies cross the street, being turned to the scientific Dark Side® after reading Darwin.  But wasn’t there plenty of anti-Semitism around already?  Didn’t Martin Luther himself write the violently anti-Semitic On the Jews and Their Lies?
This bypasses the issue: Is evolution correct?  Bringing up eugenics is not only flawed but irrelevant.
It’s the white flag of surrender.
