That's a fallacy based on the stern supposedly protecting the rudder from behind. Unless half your stern is dragging in the water, a large wave crashing from behind will put just as much stress on an inboard rudder except that the stresses aren't visible from the cockpit and are transmitted into the rudder tube instead (not "felt" at the tiller so much).

Because it isn't protected by the stern, a transom-mounted rudder is certainly more likley to be damaged if you're not careful whilst reversing into a marina pen or when launching off a trailer (in which case you'd damage your stern instead), but, as ST pointed out above, for most people the advantages of being able to more easily fix a transom-mounted rudder outweigh any apparent disadvantages created by the location.
