Perhaps Mbalula should read his Amilcar Cabral notes, again...

"We are fighting so that insults may no longer rule our countries, martyred and scorned for centuries, so that our peoples may never more be exploited by imperialists not only by people with white skin, because we do not confuse exploitation or exploiters with the colour of men's skins; we do not want any exploitation in our countries, not even by black people".
