When I was in university I took an Ethics course. One chapter in the textbook addressed Jehovah's Witnesses and the Blood Issue. I chose that to write my paper. At the time I was POMI.
I went to McGill University's Medical Library which is huge. I looked up every article I could find that supported the JW belief in blood transfusions. There were a lot of them. And I got an A++ on the paper. My professor wanted me to get it published. I couldn't do it even though getting it published in a major medical journal would have been a real coup.
It took me a few years and getting to POMO before I realized the problem with the paper.
It was severely biased, one sided. No journal would have accepted it despite the mark I got from the professor.
Good research requires that you look at BOTH sides of the issue. And I really didn't do that.
So, why am I telling you this?
Because the mountain of evidence that the WTS is wrong about the dangers of blood transfusions is completely false.
Things happen which is why they ask you to sign a release. The Dr. will give you all the information you need and answer all your questions. Honestly.
You can ask for no family to visit. That way they won't know what you are getting. Or depending on your relationship don't tell them anything. Just go get it done.
But don't risk your life for a bunch of half-truths and out-right lies.
Dangerous? Maybe. But so is crossing the street in some places. The medical profession does its very best to minimize the dangers.
Save a life. Yours!
