The story, as I remember it, is that the JWs of that country were still practicing watchtowerism as it was when they were still in contact with Bethel, which was when Rutherford was still alive and kicking!
Might be a nice sociological study subject regarding the claim that a lot of JW's from that era were real jackasses by:
1. putting their foot in the door when the homeowners tried to leave
2. playing loud obnoxious phonographs on front porches and...
3. blasting "sound car" talks in neighborhoods
Reminds me of that poor deceived Japanese soul that stayed in the jungle for 40 years after WW2 ended because he was taught that the allies were canibals (worldly people)
