This article is an analysis of hate speech directed against Roma minority based on Internet memes (colorful pictures with comments on leisure and entertainment websites). It explains legal functioning of this phenomenon in Poland and indicates related dangers. The article presents a sociological research which demonstrates that Internet memos, to a large extent, shape a negative opinion of young people on Roma minority and contribute to the consolidation of harmful stereotypes. In extreme situations, they may also lead to open hostility and violence. The author suggests that especially teachers and informal educators conducting classes on Roma community must pay attention to this phenomenon.
