Get Die Schweigespirale als Methode zur Untersuchung von PDF

Get Die Schweigespirale als Methode zur Untersuchung von PDF

By Nils Fricke

Studienarbeit aus dem Jahr 2014 im Fachbereich Ingenieurwissenschaften - Nachrichtentechnik / Kommunikationstechnik, Otto-Friedrich-Universität Bamberg, Sprache: Deutsch, summary: Europakritische Stimmen aus verschiedenen europäischen Ländern gab es immer. Der Zuwachs aber, den rechtsradikale Parteien in den vergangenen Jahren im Zuge der Wirtschaftskrise und den Fiskalpakten europaweit verbuchen konnten zeigt, dass nationalistisches Gedankengut in Europa wieder im Aufschwung ist. Ziele der Hetze sind schnell gefunden, die Parteien vom rechten politischen Rand wettern gegen Asylpolitik, Sozialschmarotzer, den Euro, Ausländer und den Islam und zeigen sich in ihrem Erscheinungsbild konservativ und europaskeptisch. Vor allem in Frankreich in shape der „Front nationwide“ (FN) und den Niederlanden durch die „Partei für Freiheit“ (PVV), erleben die ultrarechten einen Aufschwung wie lange nicht, und die nationalistischen Interessen werden öffentlich kundgetan. Auch in Deutschland bildete sich im Jahr 2013 mit der „Alternative für Deutschland“ (AfD) eine europakritische Partei, die sich zwar selbst nicht als rechtspopulistische Partei sieht, aber dennoch als Auffangbecken für rechtsradikale Randgruppierungen dient. Die Fusionierung nationalistischer Kräfte in einer Partei ist in Deutschland – anders als in den meisten Nachbarländern, wie beispielsweise Frankreich, Dänemark und den Niederlanden – noch nicht gelungen (vgl. Oliver Decker, 2012: S.15). Daher stellt sich die Frage, inwieweit der nationalistische Gedanke in der deutschen Bevölkerung vertreten ist, und in welchem Maße dieser öffentlich kommuniziert wird.
