Son of the movement, not family
Mbeki was raised by a father, Govan Mbeki, who treated his children as cadres of the struggle rather than as sons, and Thabo left home young and never saw him again for decades. Gevisser reads Mbeki's later reserve, aloofness, and inability to show vulnerability as the product of a self formed around the organisation instead of intimate bonds. The mechanism: when a political movement stands in for the family, loyalty and belonging become conditional on ideological performance, and emotional life gets rerouted into abstraction.
