“Racializing nation(s)” starts with sharing my personal stories related to race, as the rest of the chapters will, and explores racialized experiences and processes of racialization in Mexico and Canada. The discussion starts with the premise that everyone on this planet perceives race according to colonial classifications as well as domestic racist “flavors.” Racism is discussed as a form of substantialist thinking par excellence (as opposed to relational thinking), supported by global white ignorance that takes the shape of structural gaslighting. This happens through power differentials that racialize bodies, groups, and whole nations. Racism emerged together with processes of power attached to modern/colonial technologies, such as the nation-state—where processes of racialization are also deeply entangled.
