For me, that the Cold War began with the US wanting to stop Stalin's plans of imposing communism on the world. Did anybody else's curriculum portray Trotsky in a positive light? lmao it's funny to imagine the weirdos who write those textbooks were trots.
We were learning about the samurai in Feudal age japan and when I asked about ninjas my teacher told me with a straight face "Ninjas are from china". No they fucking aren't I want to learn about ninjas. Also that Malcolm X was bad because he was "violent" which was more of a fucked up and reactionary thing to teach grade schoolers, But My 9th grade history teacher straight up lied to my face about ninjas and I believed her for a couple months.
