Frida Cartas (Mexico), from Mazatlán, describes herself as a housewife and part-time writer. A former presenter at the Instituto Mexicano de la Radio with the programme Altersexual (a sexual anthropology programme) on Radio Ciudadana, she contributes to digital media outlets and gives workshops on sexual and reproductive rights for young people, with a class and gender perspective. She is also the author of the extraordinary novel Transporte a la infancia, which, using honest, colloquial language, recalls the scenes from her childhood in which she discovered and affirmed her identity, creating an essential testimony for the recognition of trans childhoods, bringing to light the urgency of guaranteeing respect, protection and freedom for trans children. In conversation with Imanol Martínez.
