When reading the context how can it possibly be, that you eat "inadvertently" an already dead animal or one torn by wild beasts? The elders had to admit, that this is not the case in Lev. 17:15.
But of course they can't agree with a view that goes contrary to what the org is saying.
I showed this reasoning to some close jw friends and also my parents.
The reaction is, that they really start to think and also to question the blood doctrine.
This is why Watchtower so heavily indoctrinates JWs to avoid independent thought and studied opposition.
If you listen you start thinking. When you start thinking you start seeing holes. When you see holes you wonder why you let holed-thinking place you and your children's lives at stake when transfusion of donor blood could help prevent premature death.
What am I saying? I'm saying any fact, factual question or rational concept shared that helps a person think (in this case JWs) helps improve that person's life.
What I like about this presentation by Crofty is that it offers a non-threatening piece of information that is something the average JW has never thought of and it might just cause them to think.
