Yeah, her most recent post made it clear.
Idk why Mauritanians and Sudanis are often grouped together... Arabized groups in both countries look different from eachother, have different dialects, different values, etc. Culturally we have a couple similarities but most of it is from Mauritanians copying Sudanese culture.
Sudanese women clothes look similar to Mauritanian clothes. But you're right, Mauritanians aren't Arabs but Berbers and west Africans. Sudanese are Afro-arabs, Cushites and nilotics.
