My response was mainly about how African history would fit into the K-12 education curriculum when it deviates from Colonialism and American History. On a collegiate level, at least in the college that I attended, there were a lot of courses available for African History. How in-depth would the curriculum go if it is a K-12 class?
I say that African history is too broad, not in the sense that it shouldn't be covered, but rather that each country can be so distinct that you can spend years going over the material and just scrape the surface. The history of Côte d'Ivoire is very different from the history of Eretria. Also, I don't know about you, but my Art History class in college devoted a significant portion to African Art (also depends on what period we are going over).
I'm not disagreeing with you, but merely asking additional information as to how the education can be incorporated.
P.S.,
My school did a fine job of covering black history. If you actually read my article, you would see that its less a critique of the lack of a figurehead, but more a question as to the long-term effectiveness of this movement vs. something akin to the Civil Rights movement under MLK., the importance of controlling the narrative, and how the goals can be better defined and more effectively attained.
