Ah yes, the annual covention reminders. Brings back memories, none of them good.
As Rebel said, the reminders are, sad to say, necessary. Which makes us wonder of course how God's Chosen People can behave so boorishly. But as already alluded to, since they think they're better than the worldlings with whom they cross paths before and after the convention, their attitude is reflected in their behavior.
The simple fact is, these conventions would not even be remotely possible without the "world". The hotels are owned and serviced by worldlings. Restaurants are staffed by them. Transportation is operated by them, streets and highways built and maintained by them. Perhaps if jws really took some time to realize that without such people and things their conventions would be impossible, they'd think twice about acting like locusts, stripping bare everything in sight.
Oh, that's right....they want to be compared to locusts, as their interpretations of Revelation indicate.
