Some blog? That talks about Spencer? That's the best you can do to come up with zingers about Darwin's "racism"?
How pathetic. Your religion justified slavery and the very colonization that wiped out the Aborigines. Colonization was undertaken to spread Christianity by the sword. Missionaries were usually the first deployed when colonization occurred. Yet you can sit and both claim that Darwinism is "anthropocentric" (laughable) and "racist", when Christians around the world were saying slavery and genocide were "God's will".
Darwin argued for the similarity of races, and was fiercely anti-slavery. He also argued against eugenics. He also said we all descended from the same animal ancestor. Yet you sneer about Darwin's "racism" when the very ideas of Darwin have led to the scientific annihilation of any support for racism whatsoever.
"What is the significance of these terms, savage and civilised? The terms [are] inapplicable and are, we think, calculated to mislead. A highly-civilised man may be a cruel, profligate libertine. A comparatively moral, nay, a truly spiritual man, a Christian, may be, if not a savage, yet certainly an uncivilised man.""
Notice your quote supposedly condemns these terms civilized and savage, but yet goes on to categorize people according to civilization anyway. All the quote is suggesting that is people from "civilization" can be immoral, and "savages" can be immoral. Fantastic. Darwin, incidentally, doesn't suggest anything different in his accounts of the morality and humanity of so-called "savage" races. But you still call Darwin a racist.
And yes, that one quote makes up for the fact that whole Christian sects were created out of a desire to defend slavery, and all the Biblical passages supporting slavery and racism (the "Curse of Ham"), and the fact that Jesus not once condemned slavery. It also makes up for missionaries colonizing Aboriginals and being the driving force behind colonization. Christopher Columbus was by all accounts, a fanatically devout Christian. I'm sure the Aboriginal peoples of the Caribbean loved him.
