I agree with jwfacts. This is perfect "we're not a crazy cult" propaganda for the wt.
Further, I am pretty sure some bigwigs from the Org came and talked to him and told him he can say that. I bet they WANTED him to say this. This kid's story isn't even about blood transfusion, right?
And I'm sure the dad will not be DA/DF. (Off topic: DA is exactly the same as DF. We should not treat them as if they are different when they are not, imo. That is just playing into the Org's word games that it uses to cover up its crimes in the minds of its people and the public.)
The wt is changing. Ask a JW on the street today and, unlike 20 years ago, they will already say blood transfusions are a conscience matter. Those that hear this story will just figure this guy's conscience is ok with it. And that attitude will spread. One day, JWs will have blood transfusions without a second thought and the whole deadly mess will be far in the past, like their previous ban on organ transplants or any of their other numerous discarded beliefs.
We know the blood thing has to go eventually. This is just another step to putting it into the past.
