'The fact that you could recieve some "acceptable" blood components but could not donate those same lifesaving yourself seemed strange. You could recieve a blood fraction but YOU couldn't give it'
Reminds me of the honor system. When you take something or benefit from something someone else donates (blood bank), you are expected to replace it with something of like value or more and so the honor system goes.
JWs are takers not givers!
Excellent thread.
