Sorry to hear about that situation with your dad jws. The more I hear about people's stories and how the org just wrecks their lives over the blood issue, it makes me want to go postal on the org. It makes my resolve even stronger to go against the borg without hiding it any longer.
I am SERIOUSLY contemplating filling out the DPA form this year, TO SUIT MY OWN PERSONAL CONVICTIONS. And to top it off, I want an elder to sign it for me as a witness. I will draw a line through any verbage which says "I will not accept blood or any of the primary components of blood." I will list out specifically what I will accept. And I can guarantee that it will include ALL of the primary components of blood. Storing of my own blood will also be accepted under any circumstances.
If an elder asks why I have altered the form, I guess that will be the time for me to come out and express my thoughts. It could very well lead to a judicial hearing, but I am fully prepared to defend the blood issue in all aspects.
I have always felt that if I were ever df'd, this is the issue it would be over. At least it can be simply and logically presented to any R&F witness as glaringly wrong. I would want all of my friends and family to know that it was the org which punished me for something they themselves cannot defend. Besides, what other doctrine carries a death warrant on human life? No other doctrine can literally kill like blood can.
