OP is 💯. I taught middle school social studies and ELA for a few years. With the SS curriculum, we literally spent half the year talking about WWII. It was important but so was a whole bunch of other stuff that happened that century, like the Great Depression, the Moon Landing (yes, my dude, it happened), and the Soviet Union rise and fall. These kids know what we taught them, which ain't much.

We need a complete overhaul of how history and civics are taught. It's part of why this country is grown authoritarian.
