According to a 2021 report by the Spanish government, hate speech has increased by 60%, with 90% of survey respondents experiencing humiliation that amounts to “hate crimes.” UNICEF has also reported a 13% increase in hate speech among young people in Latin America. Both institutions have responded with regulations and campaigns to combat hate in educational systems and society at large. This chapter presents new narratives that have been used in the Musik Thinking (Barcelona) and CoCritic.Ar (Latin America) projects, in which, through education, mechanisms are provided to strengthen critical thinking and initiate processes to deactivate hate speech, especially those directed towards immigrants. The results of the process show how music in music thinking and critical literacy, collaborative work, argumentation, and transmedia narratives in CoCritic.Ar generate spaces for citizen discussion to respond to the increase in hate speech occurring in the Mediterranean and Latin America.
