In other words it is more significant that they are civilized than "Caucasian". I might also add that Darwin's view that savage peoples were headed toward extinction was reasonably well justified, as a sheer fact, by his own observation. In South America, in Australia, and possibly elsewhere he saw or heard of native people being warred upon, or even hunted down and killed for bounties. By Christians who were by no means evolutionists, I might add.
Darwin, as I have said, was a culture chauvanist on behalf of his own Victorian civilization, but remarkably free (in the context of his time) of racist views. As I have also noted the book you quote from definitively destroyed the (originally creationist) school of thought that the races of man comprise separate species. Darwin argues that man is a single species, highly variable, but with the variations within races greater than those between them.
Darwin's fascination with the small details of human variation, his omnivorous collection of accounts from a wide variety of observers, his practice of rehearsing and examining the strongest arguments both for and against a point before forwarding his own conclusion, and even his morbid concern with the degeneration of the human stock (steming from the fact that he, and many of his children were sickly, which he feared and suspected was the result of his marrying a second cousin); all of these things provide many opportunities for painting a distorted picture of Darwin's considered and general views.
Your quoting mining is a long and continuous lie. It is intellectual masterbation. You care nothing and know nothing of the real person or of his work. I seriously doubt you have every read a single one of his books straight through, or even a biography.
Nonsense, the Turks were not savages, by any concept of civilization they were civilized. This was just racism. You also show the evil done by Darwinism in your very own words - those who win are good, those who lose are evil. Survival of the fittest, winning is everything, who cares about morals, the ends justifies the means and all those other totally despicable, totally unChristian ideals that his barbaric ideology promoted. Your words show quite well why I say that evolution leads to atheism and to loss of religion. Darwinism is the complete opposite of Christianity and each step someone takes towards it is a step they take away from Christianity.
