Pace, I suspect you may be mixing deck/aircraft angle with AOA the angle of the wing to the relative airflow. At higher speed, wing DOES stall at the same stick position (as close as I can measure it), but at significantly more G loading (provided the wings don't drop off..) throw in a bit of rudder and its called a flick or a snap depending on where you're from. Not something to do in a PA28, but they fly by the same aerodynamics as the pitts, decathlon etc.

If it was as simple as that it would be an easy task to make stall free aircraft right from 747s to 152 by limiting the stick movement to just before the stall.
Sadly it isnt that simple.
Aircraft manufacturers would not need to bother with all the expensive gizmos to prevent a stall in heavies but would have a simple stop before that AOA is reached .
