Pistoff, I like your username.
I agree they are slowly trying to discontinue this practice. Obviously the older witnesses will feel a stronger tug in their conscience than the younger members. Accepting blood for them would be a major sin. Eventually the doctrine will phase itself out. It would be nice if the society would just be straight up about things but if they are, it may be too much of a shock. Its much better for them to wait for the older members to die off first.
