Explain the difference in learning about the arrival of Huguenot and learning about kliptown in 1995 according to thami

Thami no longer cares to learn what they want to teach him in school. While schools teach him the history of colonization in South Africa. Thami thinks that the truly important events in South Africa’s history are the Congress of the People in Kliptown in 1955, the Sharpeville massacre in 1960, and the Soweto uprising in 1976. Thami isn't interested in white colonial history.
