dadkaan isku dhaqan iyo diin manihin, free movements is recipe for a disaster, mida kale is it only Bantu who are advocating for this, i've never seen the East Africans or Arabs supporting this idea.
I used to be a general unionist type of thinker but as I've gotten older and less "naive" I kinda align with you. Let's be real here, Europe is not a continent. It's an oversized peninsula where 99% of the ethnic groups speak within one language family from as recently as the Bronze-Age and while the Northerners and Southerners don't look the same and have some different dhaqan they're all mostly Christian, even if the denominations differ, and there's enough phenotypic similarity and overlap as well as shared history to make melding to that degree economically and politically feasible.
Niggas, Africa is this big:
Three dominant language families, some sprachbunds and several isolates. A big Muslim Vs. Christian divide and plenty of phenotypic diversity. Yes, all Africans are on some level connected and have been in some historical contact. There's even some evidence that Afroasiatic, Niger-Congo and Nilosaharan might have ancient ties but lets still not understate just how different the continent is as a whole on a more recent level.
I really only see internal unions being possible like between the MENA bunch or the Niger-Congo bunch but the whole continent? Idk, nigga.
