Darwin was a product of his time. He has lttle or no contact with any Black people.
He did not know any better. Darwin was only the founder of the evolutionist movement. Rather like the Montgolfers were the founders of aviation.
Since Darwin, there have been thousands of biologists and other scientists studying evolution. You ahe only read criticisms of Darwin, you know nothing of the scientists that have come afterward.
You have no such excuse, and are the one who is posting here that lighter skin color is "more civilized".
So Neil De Grasse Tyson is to you "less civilized" that David Duke because of his skin color? ABSURD!
Civilization is mostly a social thing, not a genetic one.
It is absurd for you to deny that you are a racist, Mark.
