Darwinism and Hitler: Is There a Connection?

The leftwing Anti-Defamation League recently denounced Ben Stein's movie Expelled - No Intelligence Allowed as having "misappropriated the Holocaust." In the film Stein spends about 10 minutes showing how Darwin's theories were used by Hitler to justify his policies of eugenics, euthanasia and extermination of "lesser" races.

Charles Johnson of Little Green Footballs agrees with the ADL. See his comments at this link.
However, the ADL arguments are disingenuous and Charles Johnson is wrong to adopt them as his own.

A recent article in National Review shows that Ben Stein was right and his assertions were based on "impeccable scholarship." The article by David Klinghoffer states that the Darwin-Hitler connection is not a new concept, and he quotes a number of scholars who have written about it. Nevertheless, writes Klinghoffer:

Reviewers in Time, Scientific American, Variety, Fox News, and elsewhere
have denounced the filmmakers for suggesting that Hitlerism without the
contribution of Darwinism would be hard to imagine...Expelled touches on Darwinism’s historical social costs, notably the unintended contribution to Nazi racial theories. That part packs an emotional wallop. It also happens to be based on impeccable scholarship.

Read the whole thing. If there's one thing Charles Johnson should remember, it is this: don't adopt leftist arguments uncritically without some research to see if they are justified.
