Carla were you responding to me or Spectrum?
I wouldn't use the word zeal, but it is admirable to be willing to endure difficulties in order to uphold what is right. The Nazis were NOT doing that at all. They weren't enduring anything--they were imposing suffering on others. Same with Satanists, Jim Jones, NAMBLA, and David Koresh. They are/were the causes of suffering, not the passive recipients of it, and they were not upholding anything that is right.
I do admire someone being willing to stick by what is right despite having very serious consequences. That is one test of true morality and internal strength as opposed to weakness and selfishness. Of course when the person's sense of what is right is tarnished by brainwashing or lies, it is sad instead of admirable.
Spectrum, the point I failed to clarify earlier is that it is illogical IMO to believe that the Xian God prohibits blood transfusions. This is supported both by what Ingenious said and also by the fact that the suffering and deaths associated with refusal of transfusions is inconsistent with the rest of the Bible's descriptions of God's will.
