@hanakoanohana And again, that is a massive oversimplification. Do you hear much about noblewomen being burned for being educated and literate? If so, give me a couple examples.
You generally don't hear about that because there were reasons. Noblewomen had access to education, even if not nearly at the same level as men. Or nuns in monasteries. They were educated and literate because it made sense. If a daughter of a wealthy merchant family was able to read the Bible but otherwise was "normal" for the time, very few people would care because that made sense for the situation.
If a random peasant (peasant means [small] farmer) woman were well-educated and knew a bunch of things no one else knew, then what would happen? You're just vastly oversimplifying things.
Here, Noelle literally says, out loud, that what the MC thinks is common among novices. It's not something that people haven't heard of. That's the problem.
