Brian Larnder, bless his soul, has written an overview (maybe a book review) of Preaching Eugenics: Religious Leaders and the American Eugenics Movement

From Brian:

… the concept of eugenics found a very welcome home among the christian faithful of the day from the late 19th Century through the first few decades of the 20th Century. The American Eugenics society sponsored an annual contest for the best eugenics sermon of the year and apparently many clergymen participated, readily supplying biblical quotations to make the case for eugenics.

AHA! I say! (see)

Go and read Brian’s post! He concludes with…

To blame it all on Darwin (and by extension all of modern biology) is ridiculous and deceitful. To take that a step further and insist that without Darwin, Hitler would never have carried out the holocaust is the absolute height of dishonesty.
