In Archiving Mexican Masculinities in Diaspora, Nicole M. Guidotti-Hernandez challenges machismo-a shorthand for racialized and heteronormative Latinx men's misogyny-with nuanced portraits of Mexican men and masculinities along and across the US-Mexico border. Guidotti-Hernandez foregrounds Mexican men's emotional vulnerabilities and intimacies in their diasporic communities. Highlighting how Enrique Flores Magon, an anarchist political leader and journalist, upended gender norms through sentimentality and emotional vulnerability that he performed publicly and expressed privately, Guidotti-Hernandez documents compelling continuities between his expressions and those of men enrolled in the Bracero program. Braceros-more than 4.5 million Mexican men who traveled to the United States to work in temporary agricultural jobs from 1942 to 1964-forged domesticity and intimacy, sharing affection but also physical violence. Through these case studies that reexamine the diasporic male private sphere, Guidotti-Hernandez formulates a theory of transnational Mexican masculinities rooted in emotional and physical intimacy that emerged from the experiences of being racial, political, and social outsiders in the United States.
