To LupyLu:
It's pretty obvious from your comments that, while your father isn't a JW, you are. As such, you have not understood what the objections of JW critics to the blood transfusion ban are. Likely, you only go on what the Watchtower Society has told you, which a bit of research will show you, is grossly biased and misrepresents a great number of things.
Very few people I know of don't know that bloodless surgery, or using a minimum amount of blood in surgery, is a good thing. But there are certain situations, usually involving trauma, where there is simply no alternative to a transfusion of, say, red cells. The Watchtower is dishonest because it almost NEVER deals with such traumatic medical situations when it discusses the stand of JWs on blood. The recent blood video made for the medical community is a case in point: not a single word is said about what a doctor should do about massive blood loss in a JW patient.
In short, the Watchtower presents a strawman argument to the medical community about bloodless surgery.
In a larger view, the Watchtower is simply wrong when it claims that the Bible prohibits blood transfusions. The Bible says nothing about the subject, so anything that someone infers from scriptures like Genesis 9:4 and Acts 15 is just that -- an inference. And we all know how many wrong inferences the Watchtower has made over the decades.
Critics of the JW stance on blood are not generally overtly in favor of using blood therapy, nor are they against it, any more than they're personally in favor of or against any other medical treatments. What critics are most concerned with is the fact that JW leaders do not allow JWs the freedom of conscience to make their own personal decisions about a potentially lifesaving treatment when the Bible itself is silent on the matter. I have no doubt that, in the long run, the Watchtower will abandon its current stand and make transfusions a "conscience matter", just as it did with taking vaccinations or having organ transplants.
For a solid refutation of the JW view on blood transfusions, take a look at http://www.jwbloodreview.org .
Anyone who is familiar with details of Watchtower policy on blood knows that it is arbitrary and inconsistent. Until one year ago a JW would have been disfellowshipped for taking a transfusion of red blood cells that had been processed into a more pure form of hemoglobin. Yet today, that kind of transfusion is allowed, because the Watchtower has informed Hospital Liaison Committees that products such as HemoPure are now allowed. HemoPure is nothing but cow blood that has been purified and had the hemoglobin concentrated. Can you explain why straight red cells are forbidden while processed red cells are permitted? Can you explain why just a year ago such products were declared to be such an offense against God that it resulted in disfellowshipping of unrepentant transfusees, yet by a simple policy change it is no longer against "God's law"? If you can, you're doing well because experience shows that not even the Watchtower can explain these things. All they can manage is some form of "this is our religious belief and you dasn't question it."
