Thanks for posting some the those links. This issue is complicated in part because of identity confusion, conflation and assumptions all on top of geopolitical/imperial &white supremacist ideology.
There has been a shift in attitude toward this subject. From a link you posted:
The first location of anything African starts with the re-evaluation of the pedagogy and paradigms. Even the most progressive minds of the African world are still responding to, and framing African history within that 15th century discovery paradigm created at the moment of European conquest.
This is something Mahmood Mamdani spoke to during a lecture at Howard and its one of the most overlooked part of African scholarship even by people who are very sincere in their efforts.
