Hi Nicki
I am a Jehovah's witness and saddened by your story.
But I fully support the Blood position, it simply did not end with the other dietary Laws which takes it beyond eating as a principle. Then if you read the scriptures involved in both the hebrew and greek, it is an explained law for our understanding "life is in the blood" and it "belongs to Jehovah" for me this takes us fully into avoiding transfusions. Fractions is just medicine creating a grey area and the society have made them a conscience decision. If there is doubt (as with fractions as to whether they can be said to be fully life blood) it is down to the individual to decide.
A recent change is...
People suffering from Myalgic Encephalomyelitis would not be allowed to donate blood in the UK.
Adding to the ever growing list of deseases that stop people giving blood because they may get past the screening process.
There is nothing this world can do (inc blood transfusions) that save lifes they can only prolong life. Only Jehovah can literally save Life.
I am sorry you have suffered at the hands of imperfection of men. From what you have said being accused of crimes you are innocent of, unfortunately this can happen but it is no reason to leave a Religion for. The shepherds are chosen to do a job but this in no way stops them making mistakes or being imperfect it is an unreasonable expectation of them this side of Armageddon.
Although bitterness has made you turn on your former Faith this is not a healthy way to be. Apostasy has no rewards at the end of it.
Acts 5:38-39 (New International Version)
38 Therefore, in the present case I advise you: Leave these men alone! Let them go! For if their purpose or activity is of human origin, it will fail. 39 But if it is from God, you will not be able to stop these men; you will only find yourselves fighting against God."
