>Are recent Somali immigrants Black? Most Somalis would say no, but our government lumps them in as Black. Somalia is no where near the Atlantic coast and the slave trade.

Idk. Different countries have different racial taxonomies so it'd be hard to establish an objective measure of who's Black and who isn't. A person who'd be categorized in the US as Black might be considered Coloured in South Africa.

I'm not sure whether "Black" in the US connotes a particular relationship to the slave trade.
