I can see a number of problems with these guidelines. There is certainly much useful information, but some serious deficiencies as well. While much can be said in terms of the benefits of respecting personal belief, and cooperating with individuals in their exercise of their beliefs; the level of cooperation that is readily apparent between Watchtower officials and the authors of these guidelines is deeply troubling. Asking someone to reject certain types of blood transfusions (and permit many others) is a very serious matter. Thousands of lives hang in the balance.
Medical ethicists and AJWRB (ajwrb.org) have for nearly two decades shed light on the level of coercion, duress and undue influence imposed by Watchtower on members to enforce compliance. The notion that a JW (particularly one raised in the religion) possess the capacity to make a free and informed choice is inconceivable to anyone who is fully informed.
WT officials continue to expand their influence in the medical community to try and mainstream their irrational views on the use of blood products. As the larger story becomes fully known, they are likely to regret their efforts at accommodation.
