One’s race does not determine character or temperament.

“The nineteenth century was obsessed with the idea that it was race which explained the character of peoples.  The notion that traits of temperament and intelligence are inborn in races and only superficially changed by environment or education was enough to blind the dominant (so- called) whites.”

Thomas F. Gossett, Race: The History of an Idea in America, p.244
