Zen said, The only component I have not found JWs to be openly accepting is red blood cells.
Hasn't this essentially been changed too, since the year 2000?
Hemoglobin, which is the same thing as red blood cells, minus the membrane surrounding the cells, is acceptable to JWs now. All the contents inside that membrane -- which is the working part of the red blood cell, the part that delivers oxygen through out the body -- is hemoglobin.
Why would whole red blood cells be needed when hemoglobin does the same job? (It really is the same thing, since hemoglobin is 97% of red blood cells, but the WTS calls it a fraction, making it ok for Witnesses to take. Before the year 2000 hemoglobin transfusion was banned.)
The one component of blood that is needed most often in a life-saving situation is red blood cells. Now, by accepting hemoglobin, the WTS has gotten around the issue that caused more deaths among JWs than any other.
Am I missing something here?
