We had a similar situation at a WT study. Except is was about Ground Zero. Apparently a brother had wanted to go to Gilead or something but he also needed ot get a job. He went on some job interviews and was hired by an employer at the Twin Towers, before accepting the position, it turned out that he was also accepted for Gilead (or one of the WT schools). Anyway, when he asked his new potential employer if he could be hired after this ministry school thing the employer said "no". So this brother made a decision to go to the school instead of taking the job.
Now over the year, this story got translated as "God protected this brother because he chose spiritual things over physical things." A sister gave this answer at the hall to a similar question and I about wanted to puuuuuuuke. In essence, what she was saying is that God allowed the death of the other 14 brothers and sisters that day because they chose to support their families? The WT conductor did not even correct the sister..
You see, this is how all those unscriptual teachings get translated through the hall. Because sister so in so said it it must be true. It gets spread through each congregation by visitors. Over time this is how pepperoni was blood, beards were bad, dresses only, etc etc. I knew I had a responsibility to approach the sister and did and I also approached an elder because I felt that it was his responibility to correct any misconception that was be born that day through his talks . You may want to do this for Sister Elder. Otherwise the other poor sheep that follow her will perpetuate the LIE.
