Just bc I live in Whiteville, doesn't mean I haven't known any Nigerians or Ethiopians. I know both intimately.
The same way Somali parents demonize AAs and call them madows, telling kids they're not allowed to hang out is the same way Nigerians have their own set of names for them. In fact, this extends to so many other African groups. In my case, even Mexicanss were not spare this treatment in the case of my parents lol. Nigerians are high achievers and have made strides, there's no doubt about that, but they're heavily on both ends of the spectrum. Sons and daughters of immigrants and lottery Visas are doing fairly well, but conversely they have a sizable propensity for crime. Ethiopians are less successful than Nigerians, but fairly so while being also less prone to crime. But there is no doubt that in both cases Black culture is subscribed to, which isn't surprising to me at least depending on the background of the individual.
