The jw's will never ever recant this policy on blood, too many people have died to date, to make any changes at this state of the game. They know any changes could and would fracture their power base to crumbles. Don't ever expect new light to appear on this subject matter because it never will.
TTO - 40 years I watched 'new light' on this subject. 2000, 2004 new light is pretty recent. It can and will change again. For pete's sake they are allowing Bovine hemoglobin now - to even have suggested such heresy as short as 10 years back would have been unheard of. Of course it will change - eventually it will be dropped - that is the way this cult works - history proves it. They will change it when the cost to maintain it is higher than the cost to drop it. Publicity on the internet makes it big news every time someone dies from this foolishness now - at some point they will step on their penis too hard and have to drop it. Sorry for the 'french'. Jeff
