Then how do you explain what happens when a wing stalls? When a wing
reaches a high enough angle of attack to stall, the bottom surface is
still deflecting air downward. Yet when the airflow over the top of
the wing detaches and becomes turbulent, most of the lift of the wing
is destroyed. If the attached airflow over the top of the wing is not
generating lift, then why does the lift disappear when that airflow
detaches?

Because the turbulent air on top of a wing during a stall pushes down
on the wing harder than does when the airflow non-turbulent.
