Religious ed period changed my life. And I never took part in it.
The suburban high school a couple of miles away had three classes of AP American History. My working class high school had four … people sign up. The minimum for a class was five. Then the chair of the history department figured out a workaround. Students were released for religious ed last period on Mondays, with the rest going to homeroom. That left the time open since none of us four left. Even more impressively, he invited us to his home one evening a week. (Ironically, he lived in that suburban school’s district.)
We used Morison & Commager’s college textbook. Opened my eyes to the patriotic lies in high school history. Made me interested in history for the first time. Several decades later, that’s all I would do.
Even at the time, though, I thought religious ed in school time was outrageous.
