Contradiction?

In "Reflections on Exile," Edward Said writes, "Willfulness, exaggeration, overstatement: these are characteristic style of being an exile, methods for compelling the world to accept you vision-which you make more unacceptable because you are in fact unwilling to have it accepted. It is yours, after all. Composure and serenity are the last things associated with the work of exiles." He also writes, however "Because nothing is secure. Exile is a jealous state. What you achieve is precisely what you have no wish to share, and it is in the drawing of lines around you and your compatriots that the least attractive aspects of being an exile emerge: an exaggerated sense of group solidarity, and a passionate hostility to outsiders, even those who may in fact be in the same predicament as you."

The idea of exaggeration seems coherent, but it seems contradictory that a hostile exile could also be described as willful. What do you think Said meant by this?
