I have always believed that this is their most critical issue,
The UN issue, while an important one ciuld be explained away, and if necessary, could be tagged on a couple of bros. as using extremely poor judgement. Many are accepting the library card excuse...(I thought they could come up with something better myself)
The molestation issue, while extremely sensitive, can be explained away as a few bad apples. And while the policy is extremely flawed, few dubs actually believe that the WT support and promote the idea of molestation. Most dubs dont engage in it, and so are able to justify in their own minds that these are real but isolated incidents. I even realize that the WT defends this position and policy more to preserve their image as god's channel above all else...not necessarily to protect the perpetrator and definitely not to protect the victim.
The blood issue though, is a cornerstone doctrine. No excuses...they taught it, they pushed it, they rationalized it, the df'd on the basis of it...as a matter of organizational policy. Lives, many lives have been lost. It would be the unforgiveable sin in the eyes of too many to have lost so many lives from a policy now considered 'old light.' They can not let it go. The cost would be too great.
In fact, in hindsight and at this point, I believe that if could they would retract the use of fractions at this point, as it is too vague and raises too many questions. Strategically, it would have been better for them if blood was an all or nothing proposition, based solely on their misguided scriptual application. They are trying to get Pandora back into the box...but it may be too late.
