Online hate speech is a type of speech that takes place online with the purpose of attacking a person or a group based on their race, religion, ethnic origin, sexual orientation, disability, and/or gender. Online hate speech is not easily defined, but can be recognized by the degrading or dehumanizing function it serves. Multilateral treaties, such as the International Covenant on Civil and Political Rights (ICCPR) have sought to define its contours. Multi-stakeholders processes (e.g. the Rabat Plan of Action) have tried to bring greater clarity and suggested mechanisms to identify hateful messages. National and regional bodies have sought to promote understandings of the term that are more rooted in local traditions. The Internet's speed and reach makes it difficult for governments to enforce national legislation in the virtual world. Social media is a private space for public expression, which makes it difficult for regulators. Some of the companies owning these spaces have become more responsive towards tackling the problem of online hate speech. The concept of hate speech touches on the clash of freedom of expression and individual, collective, and minority rights, as well as concepts of dignity, liberty, and equality. It is not easily defined but can be recognized by its function. In national and international legislation, hate speech refers to expressions that advocate incitement to harm, including acts of discrimination, hostility, radicalization, verbal and/or physical violence, based upon the targets' social and/or demographic identity. Hate speech may include, but is not limited to, speech that advocates, threatens, or encourages violent acts. The concept may extend also to expressions that foster a climate of prejudice and intolerance on the assumption that this may fuel targeted discrimination, hostility, and violent attacks. At critical times, such as during political elections, the concept of hate speech may be prone to manipulation; accusations of instigating hate speech may be traded among political opponents or used by those in power to curb dissent and criticism.
