Document this slur, or retract it. I insist.
Before you play "the race card", be sure you know what you're talking about.
In all of Darwin's writings which I have read, he took great pains to state that he considered all living races of man to be equal intellectually and spiritually. And that's especially admirable given the era in which he lived and the "conventional wisdom" on race at the time.
I think he knows what he is talking about. And I think you are a fool if you believe Darwin wasn't a racist.
