Fishy - at long last you are starting to demonstrate an interest in engaging in a genuine conversation where you really attempt to grasp the position of the person you disagree with. In your previous post but one you have made a very good attempt to summarise my position accurately. Thank you..
Here is the key piece of data you are missing with regard to Gen.9:4. The whole point of Genesis 9 is that god is giving Noah and his descendents permission to kill animals for food, therefore there is no conflict with Lev.17.
If you bear in mind this simple principle every single word the bible says about blood makes sense: there is no contradiction....
Blood was sacred insofar as it represented a life that had been taken by a human.
