Why did Obama use the N-word to describe his grandfather?

• In one of the most remarkable passages in Barack Obama's "Dreams from My Father: A Story of Race and Inheritance," he uses the terms "collaborator," "Uncle Tom," and "House nigger" to describe someone he detests.
• he views people who disagree with him—including members of his own family—in terms of ideological kinship or betrayal
• By the time Onyango was 25, Kenya was an official British colony. Onyango was a house servant in Nairobi. He had to carry around identity papers that included evaluations of his previous domestic work.
• During the Mau Mau rebellion in the 1950s he was detained in an internment camp
• So far we might expect that Onyango would have his grandson's full sympathy, and this indeed was the case.
• It is what followed in Onyango's life that got Barack Obama thinking very differently about him.
• Throughout his life, Onyango identified the British with civilization and progress. 
• From Obama's point of view, Onyango's unforgivable heresy was not merely his admiration of the British, but how this man contemplated the differences between Western and African ways.
• Onyango's favorable disposition toward the West, provoked in Obama a visceral reaction. Obama reports that as he heard Onyango's views, "I...felt betrayed."

If you can think like Sun Tsu, then you can see the way Obama sees this country.  The people need to be lied to in order to defeat them.  According to Sun Tsu, warfare is all about deception.  Obama needs to deceive the public in order to conquer them, and impose upon them his will.  So, he misrepresents himself to the public.  He misrepresents his true intentions.  That to me is what the significance of this is.  Obama is at war with the American people.
