Cause Wessi's had a hunt and political dogfight inwards towards Anyone with Nazi ties to the ww2 regime
What makes you think that?
There was no HIAG in East Germany, there was definitely no Vertriebenen-Verband in East Germany etc., etc., etc.,....the old Nazis in the GDR were now all in the SED... the torch marches, the uniforms, the oath to the destroy their "enemies" were not that different after all...and the mindset was the same!
What you are probably thinking of came a generation later, as the old Nazis retired and died off...as their children and grandchildren startet to get interested, as it was safe to do so because that history became far removed, physically and psychologically.
For example the first real exposure to the horrors of the holocaust happend for most Germans not in school or some "denazification" measure by the occupying forces but some TV mini-series aptly named "Holocaust"...in 1978.
I read that was the moment as many younger Germans started as questioning their elders...that started a flood of articles, books and more movies....but before that? Not much...and that was about the Jews!
My own exposure to WWII happened in school, a former inmate of Ravensbrück told us schoolchildren from the horrors of the camps, we visited Buchenwald...our heroes were communists like Thälmann and our soviet communist liberators...Jews not so much.
