The single most important reasoning you can point out to a jw is regarding these passages:
"...Out of respect for God's law, they also do not accept the four primary components of blood: red cells, white cells, platelets, and plasma.
11 Today, through further processing, these components are often broken down into fractions that are used in a variety of ways. Could a Christian accept such fractions? Does he view them as "blood"?"
The same reasoning that the WTS provides for "fractions" can also be used regarding the "four primary components" as well. Further, they state:
"...They may reason that at some point fractions that have been extracted from blood cease to represent the life of the creature from which the blood was taken."
This is the key. How is it determined(who determined this? WTS? Medical field?) which part of the blood, component or fraction, represents the life of the creature? Because I can pretty much guarantee that if you were to remove any specific component, or even a very minor fraction from the bloodstream for that matter, you're going to die. EVERY fraction spoken of in this article is necessary for humans to live. The way the WTS presents it, a "fraction" such as hemoglobin is acceptable because it would no longer represent life once fractionated from red blood cells. But let's say you removed all hemoglobin from your body - what is going to happen? Will not your life end suddenly? Of course it will! The WTS will never address this argument in print. They pretend to make it appear as if whatever is acceptable is something your body can do without.
