My claim is twofold: any child that walks out of such an "art" class saying they like art is in need of a dire intervention and/or therapy, and that (modulo metaphoric license), that is basically how we teach "math" in most schooling systems I know (or rather arithmetic).
We show little empathy with kids about why they're learning a particular system, punish them based on our predetermined system of axioms without explaining why we chose such a system over many others, and people just learn to game the system enough to evade punishment (we're only talking about harsh impacts to your future economic prospects here!).
Why are we learning about these numbers and not others?
Because they build up to calculus and we've "decided" as a society that that goal is what will make you most productive.
How do we know these are the only kinds of numbers that have these rules?
There might be many! But you better learn these or else!
Why not choose different rules for our numbers? Why not have different axioms for our geometry?
We'll have none of that nonsense here you lil' insubordinate rascal...
Do we really need to optimize those missile trajectories?
Alright, that's enough thinking about where the tools we teach end up being applied.
...and so on.
Yes: some form of rote practice is needed to gain basic mathematical acumen - but nowhere near the level of attention that it deserves. Spelling drills are necessary to manipulate language, yet spelling bee championships do not poets make; neither should we conflate arithmetic worksheets and piles of homework with exercises in mathematical thinking.
Worst of all, I think is that people don't even have the vocabulary to know the worlds they aren't seeing. This is in contrast to musical experience - even if you never hit a solid note on your recorder, you can still appreciate songs and dance beyond your classroom disappointment. But how would you explain to someone that Daft Punk, Dolly Parton and Beethoven can coexist in the same universe of musical enjoyment if their (let's imagine for sake of argument) only musical exposure in life were the beeping of an alarm clock?
You'd get a lot more people traumatized about art and music class, and if I was a musician in that world, I'd also field a lot of people dumping their childhood traumas on me because I was "into music".
