The following quote surely does not represent all black South Africans in the fight against apartheid, but it is a view that a significant number of people believed:
"In pursuing our struggle, cognisance must be taken of the fact that our flight is all-embracing and is against the whole system of white domination. It is therefore unwise to waste valuable time and energy at conference and conventions whose chief aim is to impose upon us a MULTI-RACIAL PROGRAMME as against a PURELY African-inspired programme....The time for consultation is over, and all that is left for us is to strike a death-blow at the monster of exploitation and white domination."
Consider this quote in the context of a struggle in which most of the world sympathized with the opponents of apartheid. Also consider how you might react hearing a similar statement from an African American in the fight against segregation in the United States in the 50s or 60s.
