Welcome to your first posting, seems you have been here in the background for a while.
I am getting the feeling that the more the WT waffles around on what part of blood is ok, what part is not, it would seem that the issue gets more and more complicated. And this blood card stuff, and the hospital liason committee? I could imagine that the ordinary witness barely knows what the real rules are anymore.
When I was in during the 1970s to 1980, none of this complication existed - it was just no blood transfusion and that was that. No liason, you or your family just told your doctor what you wanted to.
Your post seems to me to be quite to the point. There just isn't any logic at all to accepting blood fractions, if you truly believe that the life-blood should be poured out onto the ground. The more they try to explain it, the more this doctrine is revealed to be phony.
As you are in the health-care industry, I would imagine you have quite a few comments of other past watchtower medical quackery. I never knew how much of that there was until I started reading this site...
