I remember checking out school library books like Davy Crockett, Daniel Boone, Wyatt Earp, Jeremiah Johnson . . . . And there were others, not all boy books.
Maybe the heroes were sugar-coated, but I got to know their names, locations, general accomplishments, and time in history.
The ‘evil’ side of their life was not needed. I wouldn’t have understood it anyway. And the culture at the time did not denigrate people publicly as a matter of course.
As I matured and learned of the ‘evil’ in us all, I could accept their foibles and incorporate them into their life history.
Things are so much different today.
Part of it is also just good storytelling. Many of those details flat aren’t relevant depending on the story being told.
I remember those, al along with Landmark history books and Colby books.
