Per request and no doubt catalyzed by various posts associating Darwinism (or even Darwin himself) with Hitler, Nazism, racism and other such fallacious attempts:

Hitler as a Christian

Hitler commonly and throughout life referred to himself as a Christian. He peppered his personal and public communications with biblical references and affirmations of his faith. Hitler believed in Jesus, he believed in Christianity and he believed - much like Abraham willing to sacrifice his own son - that he was doing the Lord's work. He stated so verbatim in Mein Kampf "Hence today I believe that I am acting in accordance with the will of the Almighty Creator: by defending myself against the Jew, I am fighting for the work of the Lord." What else is there to make one a Christian than personal affirmation in belief? As follows below, Hitler often referred to his beliefs, but his belief was also confirmed by clergymen of his time. The Catholic Cardinal Faulhaber of Munich visited Hitler at his mountain retreat at Obersalzburg in November 1936 and confirmed:

"Without doubt the chancellor [Hitler] lives in faith in God. He recognizes Christianity as the foundation of Western culture." Cardinal Faulhaber [quoted from Helmreich, p.279]

Darwinism and its influence on Hitler and/or Nazism, etc

Social Darwinism had its beginning before Darwin under the name eugenics - and in fact to a clergymen named Thomas Malthus, as well as Francis Galton, Spencer and others. Evolution does not teach that one race will dominate over another. Hitler abused science to justify his abuse of religion and thereby people. His views were not based on Darwinism, but rather his religious beliefs. Darwinism appeared to support his case, so he twisted it to fit his purposes; which is what many Christians try to do with Nazism and Darwin. Darwin's theory of evolution having been misapplied via the biological principles of natural selection to the social, political, and economic realms led to people trying to place themselves above others. Elitist mindsets seek to support their confidence and elite status (as they perceive it) whenever they can and to whatever distortion is available. 

"In the interest of reducing the proportion of the "less fit" in society, eugenicists in the United States helped restrict immigration from Eastern and Southern Europe. They promoted the passage of eugenic sterilization laws that disproportionately threatened lower-income groups. The laws and programs they fostered supplied a model for the Nazis, who sterilized several hundred thousand people and, brandishing their research into the genetics of individual and racial differences, claimed scientific justifications for the Holocaust." - In the Name of Eugenics, Daniel Kevles

Hitler never mentioned Darwin nor did his view of nature reflect any substantive understanding of evolution. In fact, Hitler's racism was based on the view that "races were created distinct by God" and he frequently cited works such as Martin Luther's "On the Jews and their Lies" as guides to his policies. Contrast that with what Darwin said "As man advances in civilization, and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members of the same nation, though personally unknown to him. This point being once reached, there is only an artificial barrier to prevent his sympathies extending to the men of all nations and races." - The Descent of Man, 1871.

 Darwin was a racist

Ad hominem arguments abound in Darwinian slander, a rather extensive article on the issue:

Darwin recanted later in life - or near his death

 False.

A story that was fabricated by a devout person named Lady Hope. Those Creationists who propagate this claim are apparently unaware of, or unconcerned with, the fact that Darwin's children (who were uniquely in a position to know) have affirmed that Lady Hope's story is false in all particulars.
