“The statistics clearly show that mass immigration increased the crime rate.” “In those cultures, violence is allowed.” “We must defend ourselves against the system.” These statements can no longer just be heard in German pubs and in certain environments. They have long since found their way into school yards and state institutions, into correctional facilities, religious communities, on parents’ meetings; even in daycare centres, educators are confronted with children who repeat what they hear at home. Supposedly, harmless words and sentences can quickly grow into attitudes and actions. The task of prevention measures is to offer different perspectives, to stimulate discussion, and to generate the willingness to consider oneself as part of a society that allows competing views as well as various models of life and belief.
