Sudan is so diverse it's crazy, not only between the ethnic groups but within them too. Weddings in my family have people that look so different but they're all the same group. My dad has straight hair and he's pretty dark skin for example. This one chick I knew in school was mahasi (nubian group) and she looked very different from my mahasi mate. She was light skin af and he's pretty dark skin with curly hair, curly hair and very curly hair. It's hilarious to me that you looked up Sudanese people in Google then compared it with a video of slaves to make an inference that you're so confident in.
