First, I didn’t see the movie, but I wanted to comment on the connection between Darwin’s thoughts and Hitler’s/the Nazis’ actions.
Ben Stein is not the first person to make this connection.
Consider that two of the “missing links” in the evolution of Darwin’s thoughts into Hitler’s thoughts are those of Francis Galton (Darwin’s cousin and the father of the modern eugenics movement) and Ernst Haekel.
Maybe Ben Stein’s claim about the connection between Darwin and Hitler is ridiculous. Maybe he is too biased. But we don’t need to take Ben Stein’s word alone as evidence. We have Darwin’s, Galton’s, and Haekel’s writings, as well as the 20th eugenicists writings. Read them for yourself and judge whether Ben Stein’s claims have any merit.
Here’s the Wiki article (and many associated links) about Eugenics:
