Hate speech is any publicly expressed opinion, which with its content insults and belittles another person, group or organization, calls for violence, intolerance, causes unrest, as well as all ironic and sarcastic comments and statements that actually represent passive aggression. With the advent of new technology, hate speech broadens its horizons and offers individuals new opportunities to express themselves. Therefore, today we are talking about hate speech on social media. As part of this master' thesis, research was conducted on Facebook, Instagram and TikTok comments that contain hate speech. All comments are divided into three thematic units: Private life of public figures, Politics and Foreign workers in Croatia. Quantitative and corpus linguistic analysis was conducted in all three thematic units,as well as a shorter analysis of emojis was added. The aim of this paper is to point out the presence of comments marked by hate speech on social media, to analyze them and point out the need to punish those who write them, and ultimately to point out the importance of raising awareness of the harmfulness and danger that arises from hate speech.
