My sister was sent to the office and questioned for having a copy of “Mein Kampf” at high school, in the ‘70s.
Mom is crazy about history and the US, and has lots of books from the enemy, including Communist Manifesto and Das Kapital. She wanted us to read them (I still haven’t).
Chinese General Tso(?) said to understand your enemy is you to be your enemy as in learn everything you can about him.
