Reducing hate speech is an important task for our society. In addition, it is critical to develop the definition of hate speech, classify types of hate speech, and decide how hate speech should be responded to in order to solve this problem and increase societal awareness. Therefore, the National Human Rights Commission of Korea has commissioned experts to research the fundamental concepts of hate speech and develop awareness tools. The results of this research are presented in the “Report on Hate Speech.” I would like to express my sincere gratitude to Seung Hyun Lee, Joon Il Lee, Gang Ja Jung, Hye In Cho, Sang Hee Han, and Sung Soo Hong, who have put in an enormous effort through discussions and writing over the past several months to enable the publication of this report. As was stated in the Universal Declaration of Human Rights 70 years ago, human dignity should not be deferred for any reason. I hope that this report will be widely used to build a foundation for a society of coexistence with “dignity for everyone, overcoming hatred and discrimination.” October 2019 Young-Ae Choi Chairperson, National Human Rights Commission of Korea
