I will start this O.P by a review of the mental conditionI I find many former or current witnesses at when they join the board :-
1. Broken relationships.
2. Lonliness/ depression
3. Guilt / shame
4 Stress/ fear
So for many it takes a great deal of courage to awaken, and I believe the fear of rejection of family and friends is the hardest stumbling block for many in leaving. However fortunately the Internet has given isolated members the opportunity to exchange doctrinal views and personal fears. Of course doctrinal views can result in heated debate, but the online community is also a place to listen and learn.
As for myself I occasionally debate on more controversial subjects, but I usually stop posting on a thread when I find it becomes to cut throat ( translation, when I realize I am making a prat of myself) Anyway my point of the OP is this board can be a wonderful social experience, it's fun joking in debates and even having a laugh, but if your are at the early stages of leaving,I think it's best to use the board as a friendly community to assist with the stress/ fear of leaving.
I say this from past experience, because when I joined I started some controversial posts,and I often made some rush statement, and not by nature being an argumentative person I realized I wasn't helping myself at that stage in my recovery by posting. I then changed my tactic and started OPs that were more relevant to my personal circumstances and I received very thoughtful messages from people who I had never met, and who didn't know me from Adam, and I felt I really got the benifit of an online community.
So in conclusion in my opinion we can get what we want from this online community, by deciding when we benifit from being armchair readers, or deciding if we want social activity and friendly support. But if we want to engage in heated debates, we need have the stuff to back up our arguments and my final lesson never post late at night after a few drinks:-)
