At one point, fascism was taught as “evil people marching with evil symbols, to do evil things, for the sake of evil”. Essentially the nazis were reduced to Saturday morning cartoon villains, erasing the memories of how they manipulated the minds of the common people.
That really wasn’t my experience when I went to school in Germany. Nazi Germany was a major topic for many years and across different subjects and included a visit to a former concentration camp. At some point it got a little tiring but it was definitely not simplified in any way.
