People have been saying this about schools since forever.
FWIW your anecdotes don't match mine. My public school stories are all about learning critical thinking, being allowed to think way outside the box, and being rewarded for questioning authority.
One time we got new math books in that were horrible. Obvious errors everywhere. The teacher gave us extra credit for spending the day finding math errors in the book.
9th grade European History started off with Monty Python and the Holy Grail.
In 10th grade sex ed students got to vote on a movie. Nerds and Goths teamed up, we watched Rocky Horror Picture Show.
In 3rd grade, a group of students opted stayed inside during recess and construct hot wheels courses (tracks and ramps) out of whatever classroom supplies we could find laying around.
10th grade parents day, my genetics teacher tricked parents into extracting frog sperm from a solution and playing with it. The students were nonplussed, we'd been working with DNA for quite a while by that time.
12th grade final report, I wrote a paper on the future of LED lighting, where I rewrired some incandescent flashlights into LED flashlights (obviously back before LED flashlights where a big thing).
8th grade final report, 30 page history of video games starting in 1970 and up until the mid 90s.
7th grade debate class, Rome VS Greece, on the side of Rome we argued that "Greece doesn't get to take credit for philosophers it had put to death."
8th grade math class, we just went and full on learned college level stats.
6th grade, I read the book Druids. For those not aware, it has sex in it. Quite as bit of sex in fact. Good bit of historical fiction though, I learned about the Romans invading England!
