Sudan isn’t a homogenous country. Some tribes Arabized some weren’t, but even the Arabized ones are culturally distinct from Arabs. White tourists visiting Sudan that've been to other Arabic countries are totally shocked by how distinct Sudani culture and social norms are so I guess that contradicts your post.sudan is totally an arabic country in every aspect but they black thou. Arabised,, the longest transformation any african country went thru, and thats cos of egypt near by.
PS: no one on either side of the Egyptian border region is Arab, thats where Nubians live
Neither, but I speak Arabic so I don’t care if someone labels me Arab
