That is simply appalling. The words that come to my mind are:
nonsense, unlearnable, faith-based, bullshit, and excuses
I'm also reminded that one doesn't really understand a concept
until they can teach it. If you can't teach me, then perhaps
your own understanding is weak.

I checked the wikipedia article for bafflegab, and found it spot-on.
We can do without the words "epistemology" and "ontology" as well.

It's not that. I think you need an overview of unschooling.

Cuisenaire rods are truly dreadful, along with the decimal blocks
and sandpaper letters. If that's c13m, then it's harmful to kids.
It doesn't get results.
I believe I even have the "children of suitable age". (all even ages
from 0 to 8) I can teach how I please, as they are homeschooled.
Those worthless c13m toys ("manipulatives") gave me an 8 year old
who was struggling with multi-digit addition and subtraction.
I cast that junk aside, and 3 months later he's doing much better.
He can handle most of the math needed for a college-level physics
course targeted at engineering students. That even includes the
bare essentials of integral calculus.

Thinkers may look down on non-thinkers, but don't knock it too much.
Being a cog in a corporation will put food on the table and a roof
over the head. It sure beats what the drop-outs face. We thus have
things like No Child Left Behind, which has done wonders for both
math and reading skills. You can't expect every kid to spontaneously
generate the sum of human knowledge by playing with plastic blocks.
Spoon-feeding facts into a kid might not be stylish, but it works.
