The connection is more cosmetic than something built out of a shared history/struggle.
The problem really lies in denying our heritage and taking up an ethnic identity/heritage that did not exist when we were formed in America through mixing of many different people groups.
That is the problem. An ADOS/American Freedman has as much connection to Africa as s/he has to Europe. Ultimately, that "connection" doesn't matter - it's useless. The only thing that matters - and the connection that is meaningful - is the one your ancestors fought and died for. Our ancestors didn't fight and die for Africa, they did so for the USA.
Our only connection is here, in America, not Africa. That doesn't mean we can't ally ourselves with Africans and build with one another, but we have to respect each other as well.
