> I think a White History Museum in Africa would be fine, but it would be about the history of white people specifically in Africa, which is not very pleasant. It would be mostly imperialism, slave trade, apartheid, etc.
That seems surprisingly narrow minded and makes me wonder whether you feel that there is a particular narrative that needs to be followed. European/white descended people and organizations have done some pretty amazing stuff in Africa. And continue to do so.
One might ask how much time must pass after an event before it is considered history? Given that the Smithsonian African-American includes sections on Barack Obama and Anita Hill, as well as photos and memorabilia relating to sports stars, including LeBron James, it seems that the necessary time must be quite brief. As such I would expect an honest White History Museum in Africa would include the many significant positives.
The black history museum is not supposed to represent the "parent country" it's supposed to represent black people in America. A white history museum would do the same.
