Also, there was a low-key alliance between the South African government during Apartheid and the conservative Zulu kingdom who were given their own part of the country to play in, and then there was a low-grade civil war between the Zulus and ANC (which included the communists) after Apartheid fell. Some would say that the Apartheid regime played divide-and-rule, but perhaps the Zulus also had their own pragmatic interests too.
Either way, a thing to watch for with these neo-sovereigntists is when they LARP as anti-colonial types and socialists from the 1960s but really they're just another clique which cuts deals with these same traditional power groups (in their own societies) to rule over the majority of the population without changing anything and keeping them poor and dependent. But they'll do a lot of kangz stuff to make people feel good about themselves.
If you mention Fanon, that sets some people's hair on fire, because he was anti-Western. But a part of the "Wretched of the Earth" was about the dangers of a corrupt national bourgeoisie coming to power while co-opting the language and symbols of the anti-colonial struggle. (Case in point: Jacob Zuma)
