Preface The problem of hate speech is one of the main issues currently facing our society. Although hatred and discrimination is not a recent problem, public expressions of hatred have increased and become more active since 2010. Expressions of hatred towards immigrants and women on the Internet have spread to offline society. Hate speech has increased towards immigrants, refugees, women, and sexual minorities concerning events such as the murder of a woman at Gangnam Station in 2016, Yemeni asylum-seekers in Jeju in 2018, Queer Culture Festivals, and human rights ordinances of local governments. This hatred has not stopped at words, but has led to threats and violence. One politician’s hate speech against disabled people is an example of a recent related issue. Increasing socioeconomic polarization have led to greater anxiety and fear of social instability, triggering the expression of hatred towards social minorities. Hate speech is now a regular event. However, many people have voiced their concerns regarding such instances and support policies constraining hate speech. According to a survey conducted by the National Human Rights Commission of Korea this year, many citizens are concerned that hate speech will lead to crime, stronger social conflicts and discrimination, and reduce the freedom of expression of underprivileged groups. Further, few respondents stated that they believe that hate speech will naturally come to an end. Hate speech not only corrupts human dignity and values, it also creates discrimination and damages social integration. Korean society does not yet have a high awareness of the problem of hate speech and has not yet developed responsive measures, with few efforts being made in the various areas of society.
