Any kind of online communication that promotes or justifies racism, xenophobia, anti-Semitism or other forms of intolerance based on hatred, including intolerance in the form of aggressive nationalism and ethnocentrism, discrimination and hostility towards minorities, migrants, and people with a migration background.
For similar definition see: Council of Europe’s Committee of Ministers: Recommendation No. R (97) 20 of the Committee of Ministers to Member States on "hate speech".
Individuals and groups can be affected by hate speech by terrorist groups or their sympathizers. As a result, they experience:
Racism and Xenophobia (discrimination based on ancestry), i.e. rumours about criminal offenses, incomplete information, subjectively filtered reporting towards other ethnic communities.
Anti-Semitism and anti-Muslim racism (discrimination e.g. against Jews and Muslims). For example, there are whole topic blogs that are devoted to inciting hatred aimed at Muslims or defaming associations and mosque communities; stereotypes of an impending Islamization are often used here.
Important: If these are not contradicted (even by those who think differently), it can give the people concerned the feeling of being excluded, rejected and not respected because of their family origins or religious affiliation.
Us vs. them rhetoric: referring to an ingroup / outgroup - e.g.: "They threaten "our" women." "Politicians support the Islamization in our country."
Deliberate dissemination of uninformed or false statements: e.g. statements such as: "The refugees do not have to pay in the supermarket.") ➜ [Fake news]
Disguise as humour or irony: e.g. sentences like: "I also want a new smartphone. In my next life I will become an asylum seeker."
Degrading and denigrating terms; sexist and racist insults: e.g. insults such as: "A woman shouldn’t be working somewhere like this.", "Go back to your own country."
Serving stereotypes and prejudices through certain terms and language patterns: e.g. terms such as: "Asylum seekers.", "Foreigners out.", "Threatening Islamization."
Generalizations: statements like: "All gypsies are lazy.", "Immigrants are stealing our jobs."
Striking imagery: racist depiction, e.g. of black people with bast skirts; images that reproduce stereotypes
