Imagine if they had just kept the name "international bible students". It would be a lot more accepted by the general population (imho), and it would give a lot more latitude to get stuff wrong. As a student, you would always be learning.
I wouldnt doubt the current GB has fits over doctrinal things from years ago, that they now have to fit in and keep making up as they go along.
Knowing what they know now, even the strong blood issue stand wouldn't have been taken, but their hands are tied.
