You were advocating medical treatment, the nature of which you neither understand, nor have the emotional ability to accept.
That is not the act of a good or wise person.
You stated that you were a staff nurse, and that is not as hoenst as saying this is driven by your beliefs.
Even within your limited knowledge you are being dishonest.
Yes, there are alternatives in some cases to transfusions. In some cases t/f is used when another treatment would have been better. A study I read of treatment of combat injuries in Vietnam indicated that medics had in many cases put too much fluid into casualties that their bodies had trouble managing.
But in many caes, the best thing to do is a transfusion.
You don't want a transfuson ?
Fine, as a scientist I accept that as evolution in action.
But what about your kids ?
Simple test for your moral position:
Your child has been in a car accident. A proper grown up doctor, one who has read books and understood them, says she needs a transfusion, esle she will die.
What does your faith say you should do ?
What if the blood transfusion will prevent the child from suffering brain damage leaving her a cripple ?
We both know the answer to that don't we ?
