Because by that metric, the commenter I was responding to would be deemed "illiterate" and not worthy of being admitted to college (in spite of being able to express their thoughts more clearly than most).

Again, I have a PhD in mathematics, and have taught college-level math 2010-2017.

I have taught hundreds of students (if not thousands), and have seen many of them hindered by bullshit stats like that in mathematics.

Mathematics in particular is an incredibly diverse field; yet people with dyscalculia feel that they "can't do math" — even though so much math has nothing to do with numbers or calculation, and would be accessible to them (had we only been allowed to teach it).

As it stands, we are judging fish by their ability to climb trees.

Now, you are free to have your own opinion (knock yourself out), but please have some respect for my experience in the field, if nothing else. I'm speaking as an educator.

And the above is something that many, many educators are well aware of, but feel powerless to change.

If you have qualified objections (i.e. based on something more than you just thinking that way), I'm all ears.
