Why can't Christians accept the fact that Hitler was a Christian

[Mister Agenda]

Nietsche wasn't a scientist, and Hitler had no interest in Darwin. He used eugenics, a sham theory pretending to be an offshoot of evolutionary theory as a justification for killing six million jews. Hitler was as antiscience as you can get.

Well then this shows Hitler did have an interest in Darwin.  He might not have come to scientifically correct conclusions or morally right decisions but he seems to have shown interest in Darwin and the theory of evolution.

Eugenics requires some slight knowledge of animal husbandry, and the idea was around in Plato's time. Sir Francis Galton systematized it and tried to use Darwin's work to support it. Since he was trying to get from an 'is' to an 'ought', his attempt to prop up his own theories with Darwin's was inherently illegitimate, IMHO.
