You said: How about Negro with a capital "N" instead of anthropologically inaccurate slang?
How is "Negro" any different than "Black"? Don't they mean the same thing?
"Negro" is a derivative of "Negroid", a classical anthropological term denoting a race of mankind, as is "Caucasian" and includes many characteristics other than skin color. "Black" and "White" are colors meant to relate to skin shades, and are inaccurate to boot.
