What is the author's tone in the nonfiction book, The Wretched of the Earth?

There is an unmistakable tone of anger, or even outrage, in The Wretched of the Earth. As the reader learns about the conditions that give rise to the author's anger, it seems completely justified. The inhumanity of the colonialists, the fear and cowardice of the black bourgeoisie, the tribal rivalries of the natives, and the failure of rebel leaders to articulate a clear vision and to educate the masses about the need for revolution draw Frantz Fanon's ire. At the same time, there is an undertone of urgency about the need for change, not only in Algeria but throughout the Third World. These combine to shake the reader out of his or her comfort zone, to thrust the issues of poverty, exploitation, degradation and injustice into the reader's consciousness so that the reader, along with the author, feels a sense of outrage and a need for justice. This approach is very effective in driving across his message, as this book continues to be read not just for its historical significance but as a blueprint for change in Third World countries and anywhere people struggle for their human dignity.
