Matthieu Grimpret’s *Traité à l’usage de mes potes de droite qui ont du mal à kiffer la France de Diam’s* is a short, argumentative nonfiction work that addresses French readers who may be uneasy with the country’s changing cultural and social landscape. Taking Diam’s as a focal point, the book moves between personal reflection, social criticism, and questions of national identity, asking how France is understood from the margins as well as from the center. Its concerns include the banlieues, race relations, urban violence, and the ways public figures can become symbols in debates about belonging, loyalty, and exclusion. The title’s direct address gives the work an informal, polemical tone while pointing toward a broader examination of prejudice, representation, and what it means to claim France as home.
