I have a couple of thoughts on the blood and Shunning Doctrines, both of which have been covered well before. here, and on J.W facts.com and elsewhere.
But I would like to point out the following, the only Scriptures they can use in reality for their Blood Doctrine are the verses from Acts Chapter 15. O.T verse are really out of the question, and dishonest to use on their part, as they do not follow most of the injunctions in there!
The context of Acts 15 is a Council of The Apostles and others in the Jerusalem Congregation, to decide what they should ask of Gentile Christians in the way of behaviours and practices etc, as Jewish Christians were demanding they comply with the Mosaic Law, or were, at the very least offended if they did not. When they get to the matter of the use of Blood, it is purely on the matter of EATING Blood ! A Transfusion of Blood is NOT eating it ! You can administer as many transfusions as you like to a person, and if you give them no sustenance, they will starve to death. Context is everything, to read more in to these verses is a blatant, and in fact, murderous Twisting of Scripture.
On the matter of Shunning, DFing, DAing, and actual Shunning, again the context of the Scriptures they use, and indeed, some of the instructions therein, do not say what the J.W org says, or do, they Twist these verses too.
To impose beliefs and actions upon their members in this way, is both dishonest and immoral. It is also murderous, many deaths from the Blood thing, including many children, and a fearful number of suicides and broken people from the Shunning.
It is also, to impose these things in this way, an Abuse of the Legal Human Rights of the victims, as shown by the recent Court judgement in a Swiss Court.
