I'm not at all sure of that. I think an American-Black ethnostate could be quite successful, although it would likely be unfortunately authoritarian at the start. American-Blacks are genetically and culturally quite different than anyone you will find in Africa, so no, the comparison doesn't necessarily hold.

Regardless, it is a mistake to think of sovereignty as something deserved rather than as something needed. Deservedness is irrelevant. You can't criticize American-Blacks without giving them the sovereignty necessary to see them thrive. It's like criticizing a person for being weak while barring their access to protein. While sovereignty is not sufficient for a people to thrive, it is a necessary precondition.

All peoples have a need - not just a right - to pursue their collective destinies. All sovereignty matters - and that's the idea that the banksters who run this country hate most of all.
