In order to develop discernment, you have to be a good listener.
Hearing is not listening. Listening is interactive: it requires asking questions about what you just heard and giving a feedback response to affirm that you correctly understood what was said.
I have noticed that many posters, instead of asking more questions of the poster, will instead, take some aspect of the post and make such comments as "I can relate to that". Then, they use the opportunity as a springboard to talk about their own situations. It sometimes reminds me of the "my dog's bigger than your dog" senerio.
Just as a hypothetical example, if someone told me they were a new pioneer just starting out and within the first study or two could not answer questions on the resurrection and had to stop the study to go home and do more research, my first question would be "wasn't there someone with you who could have answered that question?" It has been my experience that a brand new pioneer would not be going out alone.
As the resurrection hope is a basic premise for the foundation of this organization, it seems that this particular doctrine would have been drilled in so much that the answers would have been automatic (like zombies, from what I have experiened). I would wonder why elders of a congregation would send someone out all alone and without proper instruction and training to represent the organization.
But that's just me. I would ask questions if I thought there were any validity to a post.
The shame of being duped is that it takes your time and attention away from others who may sincerely need help.
For instance, I noticed someone from the medical profession in ER submitted a serious concern and it took a very very long time for anyone to notice him. A JW possibly needing a blood transfusion came in to the ER last night. Maybe he needed some help to talk to her. Maybe a conversation here could make a difference in saving her life.
When Drama Queens take all the attention on the board (and by drama, I mean how many different issues can one person have in 24 hours????) others who may truly need help do not get it.
