When the Watchtower dumped Peter's words in Acts 15, they lost their AUTHORITY to discuss the issue.
I happen to believe now that "abstain from blood" was a dietary protection rather than a medical statement.
In 1997, I turned down blood after a car accident that could have led to my death. It didn't as you can see, but I have a change of heart on the issue of blood because of all the fine information and arguments that I have seen on this DB.
But, in all seriousness, once the WT left the basic premise of Acts 15, "abstain from blood', there was no longer any basis for their discussing the issue.
They are a religious (false) organization, not a medical organization. They should keep their mouth's shut and their non-Bible based opinions to themselves.
I can see Jesus Christ and Jehovah sitting up in heaven saying that the sheep should be scientists.
