Book excerpt: Diversity and Homogeneity explores current issues related to the nation, ethnicity and gender in literature, film, media and theatrical performance in both the UK and the USA. Employing a broad research framework, it investigates the problematics of migration, nomadism, nationhood, citizenship, patriotism, terrorism, totalitarianism, social and racial equality, as well as masculinity and femininity in modern multicultural societies. Keenly attuned to questions of alterity, social and cultural fluidity, and heterogeneous forms of identity, yet also sensitive to contemporary unifying tendencies informing an increasingly globalized world, the volume’s contributions critically interrogate and challenge the traditional notions attached to the three overarching categories of the book’s title.
