As far as I know, Africa isn’t monolithic and never was when it comes to the different nations, kingdoms and ethnicities. The kingdoms that predated modern African nations such as the Baganda and Yoruba kingdoms should tell you that Africa wasn’t that monolithic from the start either. For instance, it’s like saying cat meat is a thing in Africa but only a handful of African nations have cat meat (Angola, Cameroon, Ghana, Cote d’Ivoire, Democratic Republic of Congo and Togo) and even then not all of their inhabitants eat cat meat.
Cat meat’s not even a thing in other countries like Zimbabwe, Zambia, Botswana, Nigeria, Tanzania, South Africa, Uganda and Rwanda. That’s like saying Asians eat dogs and this is confined to only a handful of countries (South Korea, Hong Kong, China, The Philippines and Vietnam) and there are Asian countries that don’t have dog meat (Thailand, Japan, Mongolia, Pakistan, Nepal, Bangladesh and India) just as not all Asians eat dogs. That risks being a racist cliche that paints and generalises either or both Asians and Africans.
That would be like saying Europeans poison dogs which’s a big deal in Germany, Austria, Switzerland and Italy. Not so much in other countries like Britain and Ireland where although it’s a problem, to my knowledge it’s not a big problem as it is in Germany and Austria. Not to mention Africa’s increasingly out of poverty, there’s a growing middle class in many African countries and there are African countries such as Kenya, Ghana, Morocco, Botswana, Egypt and Namibia which are in the third stage of the demographic transition model.
As in declining death and birth rates, increasingly becoming stable. That’s where several of them are, many more will join in the future. There goes another problem with generalising Africa, it ignores whatever political and cultural differences they have where Nigeria will be different from Ghana, Kenya’s different from Uganda and Rwanda and so on. In fact, even in Nigeria there’s a difference between the Muslim North and the Christian South. This is also felt to some extent with other West and Central African countries, though not as deeply as in Nigeria where at some point it was two different countries.
So Africa’s not a monolith, it never was a monolith when it comes to the Akan Empire overlooking both Cote D’Ivoire and Ghana, the Yoruba kingdoms of Benin and Nigeria and the Cameroonian fondoms.
