What's a new Afirkan breh?
If you referring to a Black woman. No, you wouldn't be that culture unless that child was accepted. Maybe a great athlete, politician or something important to society.
Davido born in Atlanta and everyone sees him as Nigerian, not AA and clearly not AADoS.
Your child would be both cultures. There is nothing else to it. That's was Naomi Osaka sees herself as Haitian and Japanese. Not one or the other. A lot of Haitians see her as there's and a lot of Japanese see her as there's. When she is more Haitian as she was around that culture more and has a family school in Haiti and she's there a lot. I am pretty sure I am more AADoS to some but I see myself as both. I don't want to say I like one more than the other. I fukk with both. I am in America so my information and research is mainly based on AADoS but since marriage, I been looking far more at what's going on in Nigeria as for the first time in my life, I know I might actually have to go back more than for family events. That clearly changes how I see my relationship with that land as now I will have stake in it. Even changes my overall take here.
This idea that you can't be both is problematic if you are. Because, that's not how reality works. At least not in my eyes. For you who's not in my shoes, that maybe different but I see myself at AADoS as much as I see myself as Brafian.
So-called AAs. I totally and utterly reject the American label/identity because this is a white supremacist settler state. You can read the article linked in my sig for more historical background, etc. on the term...
My child would have that cultural influence from the new social context they live in. But because neither I nor my wife would be from that nation, our child's ancestors did not participate in creating that culture. We wouldn't be from that ethnic group. Osaka sees herself as Haitian and Japanese because her parents are Haitian and Japanese... she isn't running around saying she's "African-American" (or another term referring to the same ethnic group) merely because she lives in Florida now and maybe listens to music by artists from the group.
I also think you're misunderstanding my point.
I'm not saying a person of mixed ethnicity can't be both groups. (that would be a dumb argument)
I'm saying that a person of African descent from another country, can't move to a different country with a long-standing community of African descent already there, with its own unique historical development, experiences, culture, and struggle, and THEN claim to be of that group or speak for that group merely because they moved there.
I have no ancestral connection to Jamaica (not anytime recently, anyway), Brazil, etc. Never would I assume the right for myself, if I moved to that country, to adopt a Jamaican, Afro-Brazilian, etc. ethnic identity (especially not on equal standing with folks whose ancestors have lived there for hundreds of years!), or to think I could speak as a self-appointed representative or authority for those groups.
I would just be a New Afrikan living in Jamaica, Brazil, etc.
