Fisherman you can't interpret God's laws concerning blood without first understanding why he had a law concerning blood in the first place. If you view all blood as being sacred, no matter where it comes from, then it is normal you end up having to try and justify why the scriptures appear to be contradictory.
Starting with the view that blood only has value if a life has been taken, prevents the scriptures relating to blood from appearing to be contradictory in the first place. It is only God's view of blood and not the watchtower's, that's important.
I am struggling to understand what it is which prevents you from seeing this. Watchtower's reasoning on the subject makes God seem foolish, a God who makes laws just for the sake of it, without rhyme or reason. Cofty's explanation provides you with the means to be an intellectually satisfied christian.
Don't fool yourself, if the watchtower could go back in time and change their reasoning they would! Just because as an organisation they have dug themselves a hole too deep to crawl out of, doesn't mean that you personally have to crawl in after them.
If it was David Splane and not Cofty who presented this reasoning you would gladly accept it as superior new light and you would be out of that hole like a bolt of lightning.
Fisherman your loyalty to man over God is badly misplaced and may even end up in your needless loss of life or even the life of someone foolish enough to follow you.
