I have observed over the years that it takes a measurable quantity for any immigrant community to assert themselves a distinct group.
Back when I was in HS, we had a Mexican family on our block. Some of them are STILL there to this day. Mainly the ones who hung out with US back then because there WAS NO large number of Mexicans in Milwaukee in the late 70s and early 80s.
There was a small pocket of PRs on the East side, still adjacent and/or mixed into the Black Community. Black people lived on the Northside and Whites on the Southside. By the mid-90s, the Southside transformed into the Barrio. When the numbers increased, they moved into enclaves of their own. Today, that's where the majority of Spanish speaking people live, from the DR and PR, to Mexico and Peru.
I was in the Grapevine's comment section under their vids on AA vs Africans topics and I'd engaged with some of the commenters there. Bolarin and other's were still feeling the sting of being called, "African Booty Scratcher" well into adulthood.
I tried to explain to them that before there were any significant Continental Africans here, I WAS the butt of that cheap laugh. That was childhood ribbing, but show me what grown muhfuckas are clowning Africans like that shit.
It was no different with any Africans though, it's completely natural to seek out your own people and culture. Back then, all that were here were the really well off who could afford to come here and attend College, etc. Now that they have their numbers up, there is a Nigerian Community Center and Ghanaians have one of their own. Jamaicans have their own Bars, barbershops, and businesses, etc.
Once any group amasses any significant numbers, they will separate themselves and make any distinction known.
Having said all of this, I am 100% in favor of Black Americans specifying our own DISTINCT identity as well. One of OUR choosing.
