Lol. But kinda true. Some of those cities have been hostile and openly racist to Africans and hence most Africans would find cities in Africa a lot more livable compared to the racist mess around the world notably in Europe, Asia and North America.
Let's all pretend that the experience is the same for everyone, if you're not white, you know this is not necessarily true for you
It’s the same with say Portland , Oregon . Living experience varies wildly on the shade of skin you have and your cultural background. And yet I see it largely on top cities list in the US.
