Booyakasha!!! (Like Ali G would say; big laugh)
When it comes to blood issues, forget about it. The little amendments made to it is as far as the WTBTS will go; and I'm even surprised they've given in that much on the matter.
You all do your thing, and let JWs do their thing; eat it, transfuse it, bathe in it, whatever, and let JWs be with their interpretation and reasoning of the text. This keeps coming up every so often; boring.
Blood is part of the deep indoctrination I can't and don't want to get rid off; don't give it to anyone, don't want it from anyone. As old as I am, have never or any member of my extended/immediate family has ever needed health treatment that could not be satisfied without the use of blood. The issue is highly hyped and overrated by the anti-JW crowd.
Give it up already. Peace out!
