I’ll tell you this from experience.
An African dropping the N word on an African-American is an instant fight. I saw it in an office once. African see themselves as superior and American blacks as criminals. American blacks know it and don’t like it.
Irony: The African was engaged in prostitution which is accepted in parts of Africa. Hence the AIDS issue. She wasn’t street walking. She just went on “dates” for money.
Considering who American black voters support, I guess melanin is thicker than water.
