The official denazification ended in both parts of Germany before 1950. All the Nazis were needed. It was not talked about what individuals had done before 45.
In the GDR it was by definition that all the Nazis had gone to the FRG. Prosecution came to a standstill. Nothing like the Zentralstelle in Ludwigsburg existed.
The silence about the time ended in the FRG with the Auschwitz trials in Frankfurt and the student movement from the mid 60ies onwards. Willy Brandt on his knees in Warsaw kicked off some hearty discussions. Later there was the Holocaust TV series with a heavy impact.
And this is the real denazification of the population. The discourse about personal responsibility for historical events changed the society. I had such Nazi teachers in the 70ies, but they got challenged by younger teachers and older pupils. My music teacher went into early retirement after he was challenged for his current and past behaviour.
This has reached about 2/3 of the population in the west. The rest is still authoritarian and votes for AFD and CDU. In the east authoritarianism is still wide spread, because challenging authority was not a good idea under SED rule. And after the Wende it was all sugar coated by Kohl.
The problem will sadly grow, I fear. Because people who are not happy with the political climate can move away. And they do it, just got a new neighbour from Chemnitz.
Poland would have under PiS, but not anymore. Unless Slovakia steps up, who would? All others see Orban as a criminal, who siphons money off and ruins his country.
