This open access book critically examines how discourses and policies target and exclude migrants and their families in Europe and North America along racial, gender and sexuality lines, and how these exclusions are experienced and resisted. Building on the influential notion of intersectional borderings, it delves deep into how these discourses converge and diverge, highlighting the underlying normative constructs of family, gender, and sexuality. First, it examines how radical-right and conservative political movements perpetuate exclusionary practices and how they become institutionalized in migration, welfare, and family policies. Second, it examines the dynamic responses they provoke—both resistance and reinforcement—among those affected in their everyday lives. Bringing together studies from political and social sciences, it offers a vital contribution to the expanding field of migrant family governance and exclusion and is essential for understanding the complex processes of exclusion and the movements that challenge and sustain them. It expands academic discussions on populism and the politics of exclusion by linking them to the politicization of intimacy and family life. With diverse case studies from Europe, North, and Central America, it appeals to students, academics, and policymakers, informing future mobilizations against discriminatory and exclusionary tendencies in politics and society.
