Apartheid scholarship’s Marxist turn internalized Western Marxism’s structuralist-versus-humanist split.

Evidence

As Marxist theories came increasingly to dominate scholarship on apartheid during the 1970s and early 1980s, the primary focus of debate shifted somewhat. With the liberal position pretty well flogged to death - at least within the “radical” camp - the principal points of contention now corresponded to controversies within Western Marxism, particularly the contest between structuralist and humanist readings of Marx (Bozzoli and Delius, 1990; Deacon, 1991). — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 565
