Bro Arab is an ethnicity not a race. Any one who speaks Arabic is an Arab. They can be white, brown, or black it doesn't. Now embrace your blackness ya aswad!Sudanis are not clear cut. They’re a diverse looking Arab nationality. Some look Arabian; some look Bi-racial & some look Black.
Arab is a sub-category under the MENA umbrella in the US census. You can argue the Arab label is one that unites the Afro-Asiatic peoples who are now all Arabs.
