I was wondering if the changes to "policy" (interesting word use to describe Bible "principles") weren't the result of some higher up becoming a hemophiliac (or some other medical necessity requiring "fractions") and needing treatment that would not be available unless they made a change in policy.
Also..... it just struck me.... animals (my cat kills the gophers) eat blood all the time.... but the Society has to to say "no blood in animal food".......
