The correct answer to this open question is the following.
You did not mention what speech from Nelson Mandela. We delivered many.
Probably you are referring to the speech he delivered in 1964 when he tried to call the people of South Africa to sabotage the racist government. If that is the case, we can comment on the following.
The generalization does Mandela makes in his speech is that he is referring to the black African people that live in South Africa.
He literally said the following, in an expert of his speech: "...Africans want to be paid a living wage. Africans want to perform work which they are capable of doing, and not work which the Government declares them to be capable [of]. Africans want to be allowed to live where they obtain work, and not be endorsed out of an area because they were not born there. Africans want to be allowed to own land in places where they work..."
That is why was considered a true African leader that fought for the civil right of South Africans during the Apartheid government. He never surrendered although he spent many years in prison and in the end, he became the President of South Africa. He was a reverenced figured in many parts of the world.
