I'm at work so can't listen to what she said, but regarding the other tweets like you have Africans who still "look up" to Euros/Whites, that's for sure. You have various things that come into place : in places that get out of of authoritarian rule there will be some degrees of "nostalgia" because for some reason people look past the bad, that's why in a lot of countries that had a dictatorship you have people who regret that period, for whatever random reason. Like in the former Eastern countries under Soviet rule, or Yougoslavia, etc. For example in CAR some people regret Bokassa because there was order under his rule and some level of development. That's why you have some Africans who talk about colonization because in that period some went to school, and some level of "development" happened. You add the decades of being brainwashed about being inferior and you end up with people saying crazy stuff. Thing is that a lot of (not all) African countrie sare chaotic now, and human beings prefer some kind of order to chaos. For some, it means ANY kind of order, even total domination. shyt just a couple days a poll in France showed that like one tenth of people would be for an authoritarian regime. I personnaly know older African folk who are well traveled, have had very good careers and are higher educated that still have some of those "White people do it better" slips. Fortunately it is changing imo, especially with Africans going abroad and seeing that the West isn't all that and coming back. There's a whole new wave now, which makes me cautiously optimistic.
About the relations between AAs and Africans never forget that Africans get white western media, which as you know portray negatively AAs. Unless brehs are into AA culture (books, music, sports, whatever) they only get the same stereotypical AA imagery...so will say : how are they (AAs) in the richest country in teh world and they don't "make it"? Which is stupid as hell bit built on that negative imagery and ignorance about the complexity of white supremacy in the US. They also hear the whole "anyone can make it in the US" mantra, so they're like "Well, you (AAs) were BORN there, why don't you make it"?. TBH, some Africans in Africa have the exact same comments about people of African who were born in Europe, because being in Africa they think it's all good here. So it's not necessaruily (only) aimed at AAs, but all Black people in the West who for whatever reason "don't make it" while they are literally dying to come here.
I personnaly myself never really understood the whole "Back to Africa" thing, I mean I do understand it but unfortunately there is mutual ignorance...fortunately I see brehs on this site that take time to study and understood more about each other so hopefully in due time some kind of better cooperation can happen but it will take time and a lot of interactions (Africans going to the US, AAs going to Africa) to better understand our differences in order to overcome them and build together imo. Actually I think low-key works of authors like Adichie are small steps in that direction, doesn't hurt that her books are great
