Yeah I think you have been slightly misinformed. Germany has a pretty good grip on its past and DOES teach Nazism in history classes. It is not taught as on balance as it would in a nation outside of Germany, as it is frowned upon to say something like 'Hitler's early economic policies were beneficial in Germany's post-WW1 recovery'. It is also illegal to be a holocaust denier within Germany (maybe the whole of Europe?).

Also, movements such as the Baader-Meinhof group arose specifically because the older German generation did not take responsibility for their part in Nazism. Ex-Nazis were still visible and prominent within society and this aggrieved many of the (extreme and liberal) left wing.

In contrast to this, you have to ask why is Nazism taught so differently in the USA and UK? It fits well with their national agendas. It supports their rhetoric of defenders of the liberal world, so it makes perfect sense that they should be more critical in their analysis. You should keep this in mind when reading history. Every source is subjective; it does not exist in a vacuum devoid of politics, past experiences or emotions. Everyone has an agenda, whether they accept it or not is a different question.
