Fisherman...
Are you wilfully misunderstanding what people post?
The consensus amongst most critics of the WT blood policy is to a greater or less extent as follows:
1 - most Witnesses will not willingly accept any procedure/product that is declared unacceptable by the WTS (i.e. whole blood + the four arbitrary components)
2 - most Witnesses will accept any procedure/product that is declared a conscience matter by the WTS (e.g. cell salvage, fractions etc.)
3 - most Witnesses will change their view on what is acceptable and not acceptable based on what the WTS say is such
4 - the WTS has consistently maintained that it is unacceptable to donate blood as shows disrespect to God's law
5 - the WTS has, over the years, had to respond to medical technology advances and has gone away from a fundamental interpretation and application of scripture to one of woolly and contradictory policy (e.g. donation is unacceptable, using processed blood fractions = acceptable)
6 - the WTS has deflected criticism that people don't have a choice by making acceptance of a blood transfusion a "DA by actions" matter. They speak from both sides of their mouth and claim Witnesses have no sanctions yet we all know DA is the same result as being DFed.
7 - the policy is so complex it requires a small army of enforcers to keep people in line and doctors fed with chaff that makes them think Witnesses have a choice
8 - a Witness can make a choice that is not acceptable one day without knowing if the policy will change the next day or vice-versa.
9 - many speculate that the WTS would like to drop the policy but since it is one of the core doctrines that has defined Witnesses as different for years and required people to make life and death choices it shies away from dropping it, preferring to dilute it to the complex mess it is now.
So in answer to the OP...
How many Witnesses would accept a treatment the WTS defines as unacceptable. A small minority.
How many Witnesses would accept a treatment the WTS defined as unacceptable yesterday but changes to being acceptable today. An almost total majority.
Forget the Bible. This is the reality.
