In the US we were just about to fight a civil war in which half a million whites died to free black people from slavery. Clearly there were many at his time that did not go along with his despicable values.
The quote I posted shows quite well that it is an integral part of evolution, let me quote it again:
In man the frontal bone consists of a single piece, but in the embryo, and in children, and in almost all the lower mammals, it consists of two pieces separated by a distinct suture. ~~This suture occasionally persists more or less distinctly in man after maturity; and more frequently in ancient than in recent crania, especially, as Canestrini has observed, in those exhumed from the Drift, and belonging to the brachycephalic type. Here again he comes to the same nclusion as in the analogous case of the malar bones. In this, and other instances presently to be given, the cause of ancient races approaching the lower animals in certain characters more frequently than do the modern races, appears to be, that the latter stand at a somewhat greater distance in the long line of descent from their early semi-human progenitors.
Darwin, Descent of Man, Chapter 2.
"I could show fight on natural selection having done and doing more for the progress of civilization than you seem inclined to admit. Remember what risk the nations of Europe ran, not so many centuries ago of being overwhelmed by the Turks, and how ridiculous such an idea now is! The more civilized so-called Caucasian races have beaten the Turkish hollow in the struggle for existence. Looking to the world at no very distant date, what an endless number of the lower races will have been eliminated by the higher civilized races throughout the world."
Darwin to Graham, July 3, 1881.
Evolution says that species transform themselves into higher species and that thus we got from bacteria to human. This makes the higher species 'better' and more valuable as the above clearly shows. More importantly, because evolution is atheistic materialism, it denies the humanity and divinity of all men and thus encourages racial and other distinctions which make it easy for racism and for racists to flourish. Let's remember that evolution considers the destruction of species a good thing because the 'cleansing' of natural selection leads to supposedly better, more advanced species. Therefore the killing of the Turks or any other 'inferior' race is completely justified to Darwin and by evolutionary theory. It is from such a milieu, such a zeitgeist, that allowed mass murderers such as Hitler and Stalin to flourish.
