I didn't want to hijack the Anderson's informative thread below, so I thought I'd post something I've been thinking about for quite awhile now, regarding children and blood transfusions.
Even the bloodthirsty god the Wits worship probably wouldn't hold it against a child if their legal guardian forced them to have a blood transfusion. Legally, morally, even cognitively children especially as young as the tyke in the story referenced cannot make decisions for themselves.
So this story, and many others, is not about the child's will but rather the parents will. Personally, I decided from the time my first child was born, if he/she needed blood they would get it on my authority. What's the worst that could happen to me? DA'd? So what? After a few years and a few "wow I'm really sorry brothers, I was under duress" I'd be back in the fold. I'd even take the heat for the missus.
As for my eternal future? Hey, Jesus died so that others may live. I'm just following his example.
Do these moronic parents even think about their options? Wait a minute, I know the answer to my own question.
As Oubliette would write, "It's a cult!"
