The black chick who plays Michonne on the Walking Dead has an interesting accent - found out her family moved to Africa, and she came back as soon as she could.
I’ve heard of blacks visiting Africa, but it is very rare for any of them to stay.
That is because they quickly find out in Africa they are not black but colored. And they are not welcomed like lost family members. And their culture and the culture of where ever they arrive in Africa have nothing in common.
I have had several Americans ask me about the kwanzaa celebration in Africa. When I tell them bluntly that it does not exist over there they don't believe it.
