Now, there can never be a lawsuit against the WTS for forbidding fractions, because the WTS gave JWs the opportunity to make their own personal decision. That's what they agree to when they sign that form, isn't it... that this is their personal decision.
What crossed my mind was that many like those above who are so confused by it all are just saying "NO" to any blood in any form.
If one of these dies and an attempt to sue the WT occurs. The WT will turn round and say "Well he/she could have had this or that blood fraction that would have saved their life. We did not ban them. So the the decision not to take blood was theirs."
