My thoughts on the subject are this, Lev.chapter 17 says that the blood is the symbol of life and to pour it out, out of respect for the animal you killed. By the end of the chapter is says you can eat an unbled animal you didn't kill and would be unclean for doing so only until evening. So this makes it clear that blood is to be poured out as a sign of respect for the life of the animal you killed, that's it period! Everything else on the matter is irrelevant.
People don't die giving blood for a transfusion so it's irrelevant. The JW religion now allows ones to take cows blood, this proves their evil Period!
There's nothing left to discuss!
If one wants to get all technical then consider this, the book of Leviticus was most likely written before the book of Genesis and the writers of the new testament we're just copying and rehashing thoughts from the old testament with out considering what exactly we're the ideas being put accross by the old testament writers. Last but not least the writings attributed by Paul contradict the writings attributed to Jesus and the four Gospels cant even get their stories strait concerning the life and travels of Christ, so burn the damn book written by ancient Talaban types and use some common sense!
And remember, the Gods loved the sweet smell of the savoury scrafice , animals being cooked as a sacrifice by Noah. Genesis. God loved the sweet smell of his sons sacrifice, Ephesians. And they call me Crazy.
