You can lie or delude yourself over that point as much as suits you, it simply is not true that “races” in Darwin's title refers to human races. Anyone who starts an article based upon that premise is either promulgating falsehood or absolutely ignorant.
Your quote was from “The Descent of Man” not “The Origin of Species”.
Americas founding fathers were slave owners, should we throw out their contributions to our Constitution because they were slave owners?
A scientist need not be above personal reproach to have contributed mightily to science.
But I guess when all you have is ignorance and hatred you have to try to find some avenue of attack, no matter how many lies you have to tell to try to further it.
The founding fathers planted the seeds that would end slavery by declaring that all men are created equal. Darwin’s theory planted the seeds of Social Darwinism, decaring that men are not created, but are at different stages of evolution, and are therefore not equal. Big difference.
