Hate speech on Twitter during the Ceuta migration crisis in May 2021

This paper analyses the hate speech in messages published on Twitter from May 17 to 25, 2021 during the crisis caused by the entry of thousands of immigrants at the Tarajal border in Ceuta. The aim of the research is to perform a thematic classification of messages with hate speech. For this, a mixed methodology has been used and six subjets related to hate speech on Twitter have been identified, of which four are focused on political issues, accounting for 80% of the messages, and only 20% of them refer to racism and immigration. In addition, up to five campaigns of unknown origin have been detected. This work concludes that hate speeches focus more on political issues than on the problem of immigration itself, its causes, consequences and possible solutions.
