Hi,
This is my first post on the new site so here goes...
I was reading the post a while back from "V" on blood policy and fractions where it was compared to a ham sandwich. This was a good illustration, but I thought it lacking a bit in that the components exist on their own as food items rather than derivatives. So, I got to thinking about what we use as a whole and a part.
Cow's milk came to mind. We use it as a raw product (albeit pasteurized) and as butter, cream, cheese, soured, cultured, and curds and whey (at least Miss Muffett did). Anyway, here is a well known product where you can use specific components.
I wrote up the detailed components of milk below but the blood policy would be akin to not drinking whole or skim milk but perhaps accepting cream cheeses or the amino acids or phospholipids derived from milk. Much like blood, the major component of milk is water.
I'm sure there are further analogies to be drawn in that it requires dairy farmers to produce milk but a JW philosophy in this illustration would forbid the collection of their own milk, they could only conscientiously get it from someone else.
Enjoy,
