Most assuredly not!!! The topic of debate, however, is that people have used Darwin's ideas to promote such racist sentiments. My point in the text you highlighted was that Darwin himself placed humans along an evolutionary continuum. Even if Darwin himself was not racist (I don't know, either way), the underlying argument in that passage has definite racist application. That's all I was trying to show.
But what an inane topic.
People have made all kinds of self serving, insane claims. There have been psychopaths who claimed God ordered the destruction of entire cities, including women, children and fetuses.
