who cares if he wasn't a "diehard racist", the fact remains that he was a racist
Obviously it does matter given the culture and ideas of races at that time. Someone who is disgusted by slavery, thought a freed black man was the nicest man he ever met and thought that all races descended from a common stock, doesn't strike me as a racist at all. Darwin is less racist than Muhammed who referred to black people as raisin heads and traded two black slaves with one white one.
