Online hate speech is a type of speech that takes place online (e.g. the Internet, social media platforms) with the purpose to attack a person or a group on the basis of attributes such as race, religion, ethnic origin, sexual orientation, disability, or gender.
Hate speech online is situated at the intersection of multiple tensions: it is the expression of conflicts between different groups within and across societies; it is a vivid example of how technologies with a transformative potential such as the Internet bring with them both opportunities and challenges; and it implies complex balancing between fundamental rights and principles, including freedom of expression and the defense of human dignity.
Hate speech is a broad and contested term. 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 been initiated to bring greater clarity and suggest mechanisms to identify hateful messages. And yet, hate speech continues largely to be used in everyday discourse as a generic term, mixing concrete threats to individuals' and groups' security with cases in which people may be simply venting their anger against authority. Internet intermediaries—organizations that mediate online communication such as Facebook, Twitter, and Google—have advanced their own definitions of hate speech that bind users to a set of rules and allow companies to limit certain forms of expression. 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. Issues around hate speech online bring into clear relief the emergence of private spaces for expression that serve a public function (e.g. Facebook, Twitter), and the challenges that these spaces pose for regulators. Some of the companies owning these spaces have become more responsive towards tackling the problem of hate speech online.
