The “safe Black” aka the African immigrant does not have the history of slavery imprinted on his/her DNA; this NAB is not “angry” because really, what do they have to be angry about? They are being offered a piece of the American Dream, they need only work hard. Which they do, supposedly in contrast to the American Blacks, who though failed by the system, are meant to bear the brunt of this failure.
Americanah is a story of love, culture shock, transition and transformation, discovery and adaptation, and finally race and hair. The latter two fascinate me because they also seem to be what Adichie really wants to talk about, subtly touches on but often does not return to.
