Denial is that generation's first, middle, and last name, dolno! Those who grew up post-war during the Economic Miracle were practically fed denial along with their mama's milk. The so-called "Rubble Years" (Truemmerjahre) taught plenty of pluck, grit, and resiliency, though scarcely humanity! I should add moreso in the former East and in Western Germany at the time.
Typically, a good way for any young German boy to get his face slapped hard by papa, was to bring up at the dinner table something he learned that day in school or might have heard about the Nazi Era, or whether daddy was part of those Mobile Jew Killing Units (Einsatzgruppen) in the East. This, usually accompanied by some
screaming, only to be placated by mommy or some other older female family member present. And then, the whole matter would be swept under the rug:-)
Two excellent books highlight this situation, "Verschollene Jahre: 1933-1945" (The Missing Years: 1933-1945) and "Papa, hast du's getan?: Taeterkinder sprechen"
(Dad, did you do that? Children of war criminals speak out).
