How does the author explain the abundance of South Africans with names for controversial historical figures like "Napoleon," "Mussolini," and "Hitler"?

The author explains that there were an abundance of controversial historical names in South Africa because black South Africans were required to give their children European names but had no context for many of the European names that they had heard on the news, much as Westerners may lack historical knowledge of controversial figures in South African history, such as Cecil Rhodes.
