It's actually quite true. Not saying it's 100% widespread, but not everyone likes the "African" stigma tied to them.
Even native Nigerians looked down on Nigerian-Americans from the time I visited years ago.
Of course there are some brainwashed people who don't like being considered African, these people are the minority and hold no power in any academic or culturally important African American community.
He said:
"How many African-Americans do you know actually consider Africa as a vacation spot? Not one... Even just for knowledge, just to know where they came from, just to get an idea of what that is; there is so much fear instilled in them that they wouldn't even want to go there to visit. You mention Africa, they start shaking."
This is fundamentally false. Especially when you consider the African basis for nearly all African American organizations as far back as the 19th century.
