can you give an example of someone being upset and what the thing they'd learned that they "shouldn't?"
as a parent I find it confusing that I'd consider getting upset if my kid was learning 6th grade history as a 3rd grader (or 2nd grade art as a 3rd grader). what actual examples are there?
the only examples of parents being upset about learning I'm aware of lately is, like, critical theory and marxism
