Um....No they're not!
African-Americans on average based on many studies have around 75-80% African admixture and so at that AA's overall genetic structure has them as mostly African unlike Moroccans who are very admixed and Algerians who are barely even African or African at all! This is the African admixture of Northwest Africans.
They can not be compared. Half of the Northwest African phenotype especially those from Algerian are not in-built African diversity.
I get what you're saying with the bolded but we're not talking about Horners and Khoisans(who are VERY African) and I never heard Horners deny they are African besides some of the crazy Somalis on the net. Anyways like I said Berbers are NOT one group there are a good amount of Berbers who are mixed or not even indigenous to Africa.
I don't know about Rwanda specifically(I hear the West favors Paul), but....
I do not understand WHY you are denial to this? Most Africans I know and mind you FIRST GEN Africans always talk about this but more importantly it was Africans themselves who put me onto stuff like this. The West constantly pimps or in nicer words exploits Africa which is why a good number of African countries are running to the Chinese. No one is making this up.
