When I conducted this turkey last time around, I researched the history and brought in a lot of interesting material that did not relate to 1914 or the FDS. That means we had a fairly interesting study every OTHER week, because as you know the pattern for this book is: first half of chapter = history of Jewish people; second half = unsubstantiated "fulfillment" BS relating to modern times.
On the alternate weeks, I would ask everyone to look up several scriptures I had researched that "supported" the WTS' interpretation, or I would share some paragraphs from an older publication which commented on the subject at hand; often these would reveal how flimsy their thinking was, or how much it had changed. Of course, I did not call this to mind; I felt I was planting seeds. This strategy came with an added bonus: often we would spend so much time reading related material and commenting on it that we would be down to only a few minutes left in the hour, in which case I would just the questions on the remaining paragraphs without having them read. A few times, I stuck my neck out ended the study a few paragraphs short of the end, saying, "We're out of time, look at that. Well, no doubt you all read the material previously. Hasn't this been a great study?" No one ever argued with me.
In the end, this process was not productive and I grew weary and realized the problems were systemic and this thing could not be fixed. I left as soon as the opportunity presented itself.
