At the moment it seems that adjustments announced so far, have been taken rather well. Parents of disfelowshipped children now have a good excuse to call them, and the new dress code has brought a bit of relieve to others.
However once the more controversial doctrinal changes start being announced (birthday celebrations and the like) many older ones may begin to privately question the Governing Body's thoughts.
But the revision of the blood doctrine in particular, is likely to bring open discontent from the Brotherhood. Because, while few Witnesses have lost family by refusing a blood transfusion, a far greater number have had operations and personality contemplated the end of their lives, over this matter. And as a result, a lot of people could become angry after realizing that they have been misled, risking everything just over an opinion.
Will many leave like the Russell/Rutherford split, it remains to be seen. However I can't see the GB have the same authority they enjoy now. And I would expect that in the 10 plan, they might move into the background once again, until the storm of discontent passes.
