I, for one, hate the current use of the word "race" toward humans (if any of you recall...). As for Darwin, just because it was the "way of the day", does that mean it's not racist? No, it is just as racist as it is today. Not all people back then "hated" Africans, Aboriginies (sp?, my appologies), Asians, Indians, "Natives", and other non-Caucasian groups (including Hispanic and Latino).
It was Darwinism (many don't associate that with Darwin, but with Herbert Spencer) that started the greatest evils in history. Nazism, KKK, and other recently started genocidal societies. They believed that certain "races", including Jews, were inferior and should be exterminated following that quote from Darwin's "research".
And saying that Darwin wasn't racist for saying that non-Caucasions are inferior is like saying that Hitler was okay killing that gross population of Jews.
FYI: gross as in large.
