What are the motifs in Hitler Youth: Growing Up in Hitler's Shadow by Susan Campbell Bartoletti?

Ignorance of the masses is a reoccurring idea in the book.

Throughout the history of the Hitler Youth is a pattern of ignorance on the part of the willful participants. This is particularly true in the case of the mass murders taking place under the Nazi regime, first with those deemed physically or mentally unfit, and secondly with the Jews and other undesirables gassed to death in concentration camps.
