Again I found the "most, some or other" JW-fractions mentioned in the text. These figurative fractions of JW seams to be used as textpattern to propaganize no-blood techniques. Figurative fractions of JW unabashedly and strategically used as propaganda tool for PBM and to implant the necessity to work with the industry. How often have these groups been used as tool?
1st group: most" Witnesses accept blood fractions is because most of them are the product of destroying blood
2nd group: some individual JWs view this as an indication that Cryo is not included in the prohibition of blood
3rd group: But, other Witnesses may refuse for various reasons
The 1st fraction, the "MOST JW are not so extreme at all", they are the cool, modern ones who support new technology and like any new apps in the onlinelibrary, they are happy about any easement, this group is the one that impresses the publicity with technical apps and pads in the ministry, the modern and "reasonable" generation which accepts scientific interpretation of old dogmas and wears apple watches.
The 2nd fraction is the "JW must have SOME very clever people among them", they have scientific educated supporters of new PBM techniques", "wise insiders", "long experienced JW" who can impress with a very good bible knowledge and exhibit medical experience, who even are able to conlude that some factor VIII and co-factors in the blood may not be included in the prohibition. Such SOME clever PBM supporters, who know the bible as well as medicine distinguish themselves as future councellors of the Governing body and press officer.
The 3rd group is the "hardliners are anyway only an OTHER negligible minority". No JW wants really to be counted to this awkward fraction, to a group who looks " for various reasons" to remain backwardly in an old book, an attitude that appears extreme and not modern. Therefore this fraction is the minority which is of little importance and not supported by most JW, who mostly would smile at those hardliners, who ignore the reasonable arguments of modern techniques used in the PBM or even may not use the new tools.
Further it seems that JW happily need not listen to or are not influenced by any trains of thoughts originating from these "most, some or other" fractions as they are making a personal choice anyway.
General strategy:
JW are good citizens and no danger, as JW "leave it up to the personal choice".
JW dont dictate to anyone anything, but before leaving it up to you, you need to worried about this moral issue so much, you need make every reasonable effort to avoid disobeying and to understand it as issue in which you can loose everything, reputiated by your family, friends and God.
