This PhD thesis investigates the humanitarian reception of LGBTI+ people from Operação Acolhida (2018-2022) as a response from Brazil to the flow of Venezuelan migrants and refugees in the country, thinking about an overview of the services offered and the issues that arise in the encounter and integration of this population in the Brazilian territory. An approach to Judith Butler s performativity supported by Jacques Derrida will be used as an analytical strategy to understand the practices, discourses, protocols and rules undertaken in this case thinking about the reiteration of norms of gender, sex and sexuality, humanitarianism and the State. In this sense, the text is a partial framing of performative reiterations of the Operação Acolhida that can (re)create unintentional (im)possibilities for Venezuelan LGBTI+ migrants and refugees. The LGBTI+phobic social reality brings with it local and international cultural crossings in which gaps, silences, segregation and violence prevail. While the humanitarian logic brings with it the narratives and protocols of crisis, of emergency, establishing haste and reinforcing constitutive absences; and the State brings with it the demand for containment, management and government of populations and spaces, creating (un)welcoming narratives. In this normative and regulatory overlap of the reception context of Operação Acolhida, the LGBTI+ migrant and refugee population needs medium and long-term integration and policies that guarantee their rights in the country. Employability, health and social assistance demands multiply in a universe in which short-term thinking is centrally reproduced. The limits, problems and advances of the humanitarian logistical structure are the focus of this work and will outline the research findings, pointing to a reflection around the adaptation of protocols and a dialogic critique.
