Your excerpt from Descent of Man neither vindicates your false claim regarding the title of Darwin's first book nor supports your claim that Darwin propigated racism. Note that Darwin does not state any one "race" as being weaker than another in the passages that you have reproduced.

OK, there's one line in "Origin" that foreshadows "Descent," as follows:

"light will be thrown on the origin of man and his history."
