I prefer the word Negro.
It refers to the people of West-Central Africa, many of whom spread and are still spreading to other parts of Africa and now into Europe. This word was used for most books and newspapers before the 1970s.
I don't like to call them "blacks". Many people in the world have dark skin, but the Negroes are different than the others: less self-control, greater tendency to violence, twice the lust but no love for women, promiscuous never monogamous, lack of insight, lack of guilt over wrongdoings, usually have proportionately longer arms and legs, jaw protrusion, masculine women, etc.
Skin color has NOTHING to do with it. I've known people from Sri Lanka who are just as dark as Negroes, but have feminine often pretty women, and are intelligent, monogamous, honest and law-abiding.
