How would you know? You're not even barwani. Some barwanis look bantu asf, I grew up around them. Some pass for arabs and some light skin Somalis. However you cant deny at least 25% to 30% look like light skin bantus, especially the ones who claim Kenyan.Troll.
Many Bantus speak Swahili and wallahi I've never seen a Barawani that looks like that. This is news to me.
You're overplaying the amount of intermarriage that happened between Barawanis and Bantus. Indeed 30% of Barawanis would pass for Arab while the rest look like Somalis but light skinned.
Maybe 10% have Bantu features but not to this extent.
