I'm not sure your intent of all these posts. I think everyone is in agreement that theft is wrong and shouldn't occur. But unfortunately it does occur. Nobody here can stop it, though there are things one can do to help prevent being a victim of stroller theft -- renting, not taking an expensive stroller, marking your stroller in a way that's easily recognizable, not leaving anything with your stroller, etc.
Honestly, with the vast numbers of strollers that enter the WDW park gates each and every day of the year, we would all personally know at least 1 family affected if this was such a big problem. While based on truth of limited past thefts, the "threat" of it happening has taken on a life of its own through the Internet.
