Ethiopians are not African American. They are Sub-Saharan Africans. Try to explain that to a black American. Africans are not African American and all Africans are not black. Only sub-saharan Africans are black. Northern Africans are Mediterraneans. They have more in common with Italians and Arabs and Persians than with Sub-saharan Africans.
Also, Most African slaves where from West Africa. They where from Modern day Senegal, Ghana and Gambia.
