I cannot speak for what happens in other countries or other more lenient/normal congregations for that matter.
All I can say is that here in NY, in jw fundie bizarro world, Golden Age's wisdom still reigns supreme. Not only do jws here believe the contents as factually correct today, they retain the paranoid conspiracy theories about doctors, medical association (as quoted earlier, thanks). This means that there can be no true informed consent by a doctor to a patient. The patient has been coerced and brainwashed into not listening to a damn word the doctor ever says.
I was recently advised not to use aluminum pans because of what was printed in Golden Age, just to give you an example.
See my old posts re the drills we had to practice how to successfully lie to healthcare personnel, because Satan was controlling them.
Now I realize I was a kid and not responsible, but my mother is still completely brainwashed by a bunch of liars. I'm honestly of the mindset that she is not totally responsible for her beliefs.
They should have stuck to the doctrinal reasons for refusing blood and skipped the medical lies. Making up lies about what medical experts said is completely inexcusable, and in US law (where Kerry practices), causes legal liability.
PS slim--Kevin Trudeau is an example of how US law protects the public against false claims. wts has made serious false claims in its history and continues to do so.
