Firstly, let me acknowledge what you said about deaths from the blood issue, versus deaths from ignorant people refusing to wear seatbelts. Well said, you're right. In terms of numbers, the loss of life from the blood issue is surely less than some other "cause" one could take up.
>>Blood transfusion does not fall into the extreme severity category (in terms of breaking the rule) and simply acknowledging that you were scared and gave in to a transfusion would qualify you as remorseful.
I've only been out of the Watchtower for three years. But having discussed issues with many ex-JW's, it seems that JW's break into segments. There are the ones that are only in it for appearances. They watch r-rated movies when no one is watching, and would probably take a blood transfusion, knowing they could "repent" later. But there is another segment (in my experience, large, if not the majority) that truly want to "please Jehovah". It isn't about "rules", it's about pleasing their heavenly father. Except they let the Watchtower tell them what's pleasing and what isn't. He hates "misuse" of blood, so they don't "misuse" it and choose to die instead. What will or won't "get you disfellowshipped" is irrelevant.
I must admit that there's another issue here. We've all been personally affected by the Watchtower. Some of us (not me) have lost loved ones to the blood issue, to suicide brought on by the effects of the cult, and were in other ways severely affected by it.
Just like a person who's been affected by cancer may take up a cancer cause, so many of us have taken up an anti-Watchtower cause. Statistically, it may not be the most efficient use of our time. But emotionally -- humanly -- it's fulfilling.
Can it be taken too far? Yep. But barring the extremes, I don't see anything wrong with a person investing some of themselves in efforts to prevent the organization that damaged them from damaging others.
Question for you: Have you read "Crisis of Conscience"?
