Xenophobia is a current topic, which has repeatedly been focused on by media coverage since the beginning of the refugee crisis in 2015. An essential reason for this is the increasing number of hate speech on Facebook, intensified by right-wing populist parties and groups. The present work deals with the development of xenophobic attitudes in association with political factors. Therefore, the research addresses the question to what extent there is a link between political orientation, political interest and xenophobia along with the role of participation in political discourse on the Internet. In addition, the relevance of personality traits as well as emotional contagion is investigated in this context. For this purpose an online study (N = 226) was implemented and the collected data were statistically analyzed.
