a study in fundy religious change

Eileen Barker of LSE / INFORM put me onto this; I'd heard rumours that the JW's were shifting abit on the blood transfusion thing a bit and lo and behold here's a pressure group partly within the WatchTower domain. Interesting things to note, imho: note the loyalty to the WTS, the pressure from people involved in pastoral situations involving the particular difficult doctrine. the gentle reappraisal of accepted teaching. Lessons here for other areas of desired religious change - do I hear Jihadist Islam?
