Okay, The WTBTS condones eating bone marrow, even though it is full of red blood cells, cos in the bible it says that the Jews ate it.
The WTBTS condones drinking milk even though it contains huge numbers of white blood cells. (As much as 750 000, and 1 000 000 per cubic centimeter) because the Jews drank it.
Query - if somebody needed a transfusion of white cells what would be wrong with getting human females to express and donate milk, so the white cells could be harvested and used? After all anybody who drinks milk consumes them every day.
Would it be okay as long as the donor was not a Dub? After all, the net result would be the same as loose conduct, allowing a man who is not her husband to suck her breasts. Since Judah could go to a Gentile prostitute without censure, presumably a Dub could take worldly breast milk-cells? This is a serious question as white blood saves lives.
