All milk contains blood. They take too literally the quote that I think is in the book of Paul, do not eat meat that has been strangled, sacrificed to an idol (holy communion or halal,mainly, maybe kosher, not sure, as it is still YHWH but they reject his teaching and son so perhaps it's not really Him they worship?) or containing blood. We can break the sabbath for mercy so we can break the no blood for medical reasons, though they argue that if you can't drink it you can't inject it. Well life giving milk contains blood and it is necessary so maybe they should just go back and reread that it is bloody meat that can't be consumed and leave it at that... But it is a cult and there is no waking people up from it until they realise for themselves, I was a JW when I was a kid so I know lol.
