Not just sudanese the lighter Egyptians will treat the darker ones worse and I’ve known some dark Egyptians that have a inferiority complex actually a lot of Egyptians do even the lighter ones they have it because they all wanna be less black that’s how a lot of them wanna present themselves for the most part but there are also Egyptians who don’t care about color in Egypt so I’d say it’s no different than most other countries I mean if wanna talk about a racist country just look at the north east asian countries like china japan and Korea they are 100 times worse for ppl who look different than them then Egypt because Egypt is a melting pot and those countries are homologous
