Question for you breh. You are in the UK, right?
Is there any beef between black Brits and Nigerians? I would assume a large amount of y'all are Caribbean, so is there any attitude you get from some west Africans in England? Presumably, they exist in tandem with you in that society .

This is a crazy question. Black British means being black & British = any Caribbean/African person born & raised in the UK.
Nigerians (born & raised in the UK) are an integral part & one of the most important subgroups/pillars of black British population. And when it comes being black British - the 3 most important/influential groups are Caribbeans, Nigerians & Ghanaians.
So, there’s no beef. Yes, in the past, there was a bit of friction between Caribbeans & Africans. But people are more integrated now. I’d say, it’s always been integrated to an extent albeit there was a clear Caribbean culture dominance. However, Caribbean culture isn’t as dominant as it once was & Nigerian culture is just as dominant now.
The next phase of black British culture is a fusion of Caribbean & African culture. And it’s already happening now with a lot of Nigerian words/slangs being an integral part of black British slangs & a lot of people trying to learn Yoruba. Growing up, even the music, was heavily influenced by Caribbean music but Afrobeats has supplanted that now. So, that as well, is symbiotically creating a new type of sound.
All in all, there’s no beef (at least in London) but sometimes you might see a bit of a tiff on social media with some people riding for their heritage, but that’s where it ends. Even with the ongoing World Cup - everyone (Caribbeans & Africans) is supporting African teams, apart from England. Jollof rice is just as popular with everyone as rice & peas is now. Some Caribbeans even eat proper Nigerian foods. Clubs play Afrobeats, ragga (dancehall), UK music & hip hop. People intermarry without any hassle. All big Afrobeats artists concerts are always filled with Africans & Caribbeans. Ditto big ragga (dancehall) artists concerts. Also, everyone’s playlist has ragga/Afrobeats/hip hop.
New immigrants from both sides might face a bit of discrimination due to them being fresh. And that’s the way it’s everywhere. But overall, everyone is calm.
