A diff is supposed to allow one side/end to spin faster than the other so why is this such a drama?

To make it easier to think about. Consider a 2wd car. Say you put a bigger tire on one wheel than the other. Since that tire is bigger, if it turns at the same RPM, it will be traveling a longer distance, thus it would try to turn the car in one direction all the time.

On an AWD car, instead of trying to turn the car, the front axle was trying to pull the car faster than the rear was, even though the two axles were rotating at the same RPM. The only thing that can give when that happens, is the tire sidewalls will deflect a little, because there is a great deal of force being transmitted through the differential and driveshaft, due to the fact that each axle is trying to move the car at a different linear speed. Eventually the force becomes too great, the tire skids and then the sidewall unloads and the process starts again, all the time, every second the car is moving. The differential will overheat doing this very quickly.
