Ha!
I knew that Christian Scientists would come up in this.
Tell me how the Christian Scientists ban on all medical treatment would effect the medical communities handling of no-blood procedures on Christian Scientist patients.
There are no Christian Scientists patients - they have excluded themselves from being considered for any medical care.
They don't qualify to be included in groups who forbid blood transfusions because their group doesn't exist at all when it comes to discussing medical care requirements.
Christian Scientists simply don't factor in when discussing blood transfusion refusal. It isn't like a doctor is faced with deciding whether to transfuse or not or what kind of medical procedures to follow when it come to the CS - there is no care - the CS person does not exist as a medical patient.
The Christian Scientist patient is a red herring - they don't exist.
