Fishy - We have had this conversation at great length and you repeatedly refused to respond to specific questions. I have much better things to do than to go through it again.
Blood was only sacred in so far as it represented a life that had been taken. It represented the life which had to be returned to the life-giver by pouring the blood on the ground - or offered on the altar where the life of the animal took the place of the life of the penitent.
If an animal was found "already dead" this did not apply - bleeding a dead animal is not possible - the life had not been "taken" and the animal could be eaten unbled with impunity. (Leviticus 11:38,39 & Leviticus 17:15,16)
If the owner of the animal buried it he was unclean and had to wash his garments and bathe. If he ate it he was unclean and had to wash his garments and bathe. There was no punishment unless he neglected to follow the procedure for removing uncleanness.
These facts are unassailable.
If you cannot see any connection between these facts and blood transfusions then I cannot help you further. They ought to at least give a JW pause before they sacrifice the life of their child.
