This is an interesting thread, it seems from all the comments, that gossip is the normal state of being for a JW.
I think perhaps this is because of the way we were conditioned by the religion itself.
When you tell someone that they are in an elite group and the rest of the world is in darkness, non elite and grubby sinners, you encourage judging.
Once you have fed and raised that trait in people, how can you tell where it will/wont pop up?
So as a result, Gods "people" (as they fancy themselves being) are the most judgmental people on earth. All gossip is judgmental in nature. Its the foundation.
Stands to reason they would use it on each other too.
