This film is cheerfully ignorant, manipulative, slanted, cherry-picks quotations, draws unwarranted conclusions, makes outrageous juxtapositions (Soviet marching troops representing opponents of ID), pussy-foots around religion (not a single identified believer among the ID people), segues between quotes that are not about the same thing, tells bald-faced lies, and makes a completely baseless association between freedom of speech and freedom to teach religion in a university class that is not about religion.
And there is worse, much worse. Toward the end of the film, we find that Stein actually did want to title it "From Darwin to Hitler." He finds a Creationist who informs him, "Darwinism inspired and advanced Nazism." He refers to advocates of eugenics as liberal. I would not call Hitler liberal. Arbitrary forced sterilization in our country has been promoted mostly by racists, who curiously found many times more blacks than whites suitable for such treatment.
Ben Stein is only getting warmed up. He takes a field trip to visit one "result" of Darwinism: Nazi concentration camps. "As a Jew," he says, "I wanted to see for myself." We see footage of gaunt, skeletal prisoners. Pathetic children. A mound of naked Jewish corpses. "It's difficult to describe how it felt to walk through such a haunting place," he says. Oh, go ahead, Ben Stein. Describe. It filled you with hatred for Charles Darwin and his followers, who represent the overwhelming majority of educated people in every nation on earth. It is not difficult for me to describe how you made me feel by exploiting the deaths of millions of Jews in support of your argument for a peripheral Christian belief. It fills me with contempt.
