I have come to believe it is part of that "high control religion" thing.
Many JWs love being one because of the inherent family/friends/belonging that they see on the surface.
The underlying fissures become evident if you are ever in a moment where the rancor of an individual peeps through...
then you will hear things like "well excuuusse me, brother"
Or a brother telling a sister as a subtle put down
"well you see, sister"
both are said with sarcasm and to remind you of your place within the arrangement.
yawn, whatever
these people are so boringly ridiculous.
