While bloodless surgery is beneficial in SOME cases (such as when a transfusion isn't really needed but is given anyway, which I think happens rarely these day with the shortage of blood available...anyway...), there are many more cases where it is medically necessary. The car crash victim for whom volume expanders will do nothing much, the mother who ruptures during labor and needs an emergeny c-section but is in danger of bleeding to death, etc. You can't say that blood is never medically necessary. And to say that the bible says we can't take blood intravenously is a gross misrepresentation of scripture.
I despise the illustration they use of the alcoholic whose doctor tells him to abstain from alcohol. "Would that mean he could take it intravenously?"... Let's see... apples and oranges anyone? Anyone?? Alcohol will NOT preserve your life (it'll pickle you pretty good, but not PRESERVE you). Abstaining from it may if you make it a habit to guzzle a 24 pack every 24 hours. Blood has been PROVEN to preserve lives and abstaining from it in a lot of cases has been PROVEN to cost lives. It's not like people are bellying up to the bar in their local lab and asking for a pint. They aren't consuming it or EATING it, as is prohibited in the scriptures. And, if you wanna get technical, the JW who orders his or her steak medium rare is just as guilty of flouting their prohibition on blood as the person who takes a transfusion...maybe moreso because they go DIRECTLY against the bible's command to NOT EAT BLOOD. Unless they slaughter the animal themselves, they can't be sure that all the blood that could possibly be drained was in fact drained. And the "juices" (as my dad puts it) still contain blood cells, whether they are cooked or not, they are still blood.
Faithful in little, faithful in much... You can't perport to "abstain from blood" and yet still eat meat lol. Unless we're just not gonna nitpick that... But yet it's fine for them to nitpick with the fractions and say "this is okay, but that isn't". It's all a bunch of confused convoluted circular reasoning. Glad I'm out of it and tore up my "Please kill me by not giving me blood" card.
