From Amin Malouf's On Identity (translated by Barbara Bray.):

But let us return for a moment to some examples I quoted at the beginning of this book. A man with a Serbian mother and a Croatian father, and who manages to accept his dual affiliation, will never take part in any form of ethnic "cleansing". A man with a Hutu mother and a Tutsi father, if he can accept the two "tributaries" that brought him into the world, will never be a party to butchery or genocide. And neither the Franco-Algerian lad, not the young man of mixed German and Turkish origin whom I mentioned earlier, will ever be on the side of the fanatics if they succeed in living peacefully in the context of their own complex identity.

Here again it would be a mistake to see such examples as extreme or unusual. Wherever there are groups of human beings living side by side who differ from one another in religion, colour, language, ethnic origin or nationality; wherever there are tensions, more or less longstanding, more or less violent, between immigrants and local populations, Blacks and Whites, Catholics and Protestants, Jews and Arabs, Hindus and Sikhs, Lithuanians and Russians, Serbs and Albanians, Greeks and Turks, English-speaking and French-speaking Canadians, Flemings and Walloons, Chinese and Malays - yes, wherever there is a divided society, there are men and women bearing within them contradictory allegiances, people who live on the frontier between opposed communities, and whose very being may be said to be traversed by ethnic or religious or other fault lines.

We are not dealing with a handful of marginal people. There are thousands, millions of such men and women, and there will be more and more of them. They are frontier-dwellers by birth, or through the changes and chances of life, or by deliberate choice, and they can influence events and affect their course one way or the other. Those who can accept their diversity fully will hand on the torch between communities and cultures, will be a kind of mortar joining together and strengthening the societies in which they live. On the other hand, those who cannot accept their own diversity may be among the most virulent of those prepared to kill for the sake of identity, attacking those who embody parts of themselves which they would like to see forgotten.
