I support what Germany has done. History and the sins of the third reich are taught in school so that students understand how the nazis came to power and the atrocities they committed. It is against the law to display nazi propaganda publicity, but items may be keep in museums. Giving the nazi salute is against the law, and, in the last 2 weeks 2 Korean tourists were arrested giving the salute in front of the Brandenburg Gate in Berlin, and an American tourist got beat up by the locals for doing the same in Munich. This is how they make sure nazis are not glorified and that it never happens again.
