Take a pencil in your hand holding the sharpened end, and hit a countertop as hard as you can with it. Now, hold resistance with it as you apply leverage and release the resistance suddenly. The pencil is going to hit the countertop with MUCH more force. That's what we're talking about. A force that engines are not supposed to get.

Stabing the throttle, even on the most responsive of systems, is going to ease up through the band. Putting it in gear will apply the 'resistance' like in my pencil annalogy. Either the car will move or the tires will spin, or the car will die. Now release that pressure in a milisecond. ALL that violent torque will hit that free spining motor with NO dampering whatsoever. And engine is not made for that. Even on a full clutch dump, either the tires break free, the car moves, both, or the car will die. OR...... something breaks.
