I’m not “missing” it. I’m just not fixated on it.

The answer got all of the following correct:

* lift is created by pressure differential

* pressure differential is created by difference in airspeed over the top of the wing

* shape of the wing is a critical factor that results in airspeed difference

All of those are true, and upstream of the thing you’re arguing about.

The answer is not wrong. It’s not even “mostly wrong”. It’s mostly correct.
