Hi Looloo, if you didn't know already, jw's are indoctrinated to believe that jehovahs organisation is perfect, a spiritual paradise. Nothing like theft would be committed by jehovah's people . . . right? Your friend was only spouting what she has been told a million times.
"Worldy People" are the scapegoats for everything. For a long while before every convention, the society sent letters to elders which were read out to the cong warning parents to not let their children wander around unaccompanied at conventions and assemblies, because some children had been molested by "worldy" people at the conventions. (And we all know jehovahs witnesses would never do something like that! ) What a cover-up! Jw's were labeled "a pedophiles paradise" by a judge a few years ago, but blame it all on the "worldlies". It's so convenient.
A family member of mine had a brand new expensive pen that was engraved with his name stolen at a kh. He left it on a chair with his books, got up to talk to friends, came back and it was gone. There were no 'worldly people' there that night. No-one to blame! After that incident, he always made sure his wallet was in his pocket when he was at the meetings.
