The main objective of this quantitative research is to is synthesized in knowing from a communication and digital culture perspective the dynamics derived from the polarization of the feminist movement in Mexico, based on the analysis of comments on YouTube and Facebook, as well as the hashtags #UNAMFeminista and #UNAMSinTransfobia on Twitter. Our object of study is the online participation of the audiences of the last forum held on March 24, 2022, entitled: "Necessary clarifications on the Sex and Gender categories", organized by the Center for Interdisciplinary Research in Sciences and Humanities of the UNAM. The use of a repertoire of digital methodologies for the investigation of content generated on Internet platforms is proposed, based on data mining, network analysis, as well as the analysis of sentiments from comments on digital social networks. The objective is to account for the main actors in the digital public sphere that influence affective polarization and the risks of communicative phenomena such as hate speech and discrimination. This research seeks to contribute to feminist movements from communication and digital culture in Mexico, given the scarce academic literature.
