Although it is not seen as a problem of high importance by Central European societies, antisemitism serves a function of exclusion and disqualification of liberal elites fostering liberal pluralism and multicultural society. Even though hate crimes are usually not being reported in the European Union, therefore the real numbers which we are dealing with can be significantly different, we cannot ignore the fact that anti-Semitism is on the rise within Europe. The overall aim of the training is to improve competences of youth workers for being capable to invent and implement youth work methods and tools on preventing and dealing with online antisemitic hate speech among young people however not excluded to Jews, but also considering minorities such as Roma, refugees or migrants. We also aim to create intercultural and interreligious dialogue, promote common values of freedom, tolerance, respect of human rights and reach young people to prevent violent radicalisation as well. As youth workers we often face violent behaviour on the internet and dealing with the topics of European values, European history, heritage or online/offline hate speech they often face issues with modern antisemitism (connected with the work of NGOs, gaining financial support, helping refugees and minorities and doing voluntary work). However, since this phenomenon is not observed and researched and taken into consideration, we often lack solutions and ideas how to react and what to do. In BPI we are currently working on the database of antisemitic hate speech which will be introduced by the end of the year and which could serve such a purpose. As most of the youngsters are not considering the online sphere as the real-life and they allow themselves to use such a language which is not accepted or would not have been used in the real-life or in a public place.
