This goes along with conversations I've had with someone I know on the HLC. We were talking about young kids (not "mature minors") and he described trying to fight blood for a young one as "pissing in the wind". He's right, they can get court orders easily and quickly and the only thing the parents get is legal bills (provided there's a non-WT lawyer involved), headaches and news coverage. He said that as long as the parent's objections are noted, they have done the best they could.
Now, maybe this person disagrees with the WTS stance on blood and is a reformer. I just don't get that sense at all given what I know about him. He's also pretty moderate as far as elders with big circuit/district responsibilities go but I don't see him as a liberal. So, maybe that's what his personal ideas are but he presented them to me as the official HLC party line.
I really think this handout is simply to save the HLC time from getting involved in every case when a young child needs an operation.
BTW - the sentence about not talking about the resurrection hope just proves how deceitful the WTS wants their followers to be. So, on the one hand, the main arguement as to why JWs don't worry about withholding life saving treatment is because God can bring the child back anyway and it's more important to abstain from "blood". On the other hand, don't talk about that main doctrine?
