"The out-of-context quotes and video edits are not an innocent mistake. That still leaves me dumbfounded"
I was already well out, no chance of going back, but not a long time out, when I first became aware of the totally dishonest, deliberate, out of context quotes and editing. These saddened me, as before that time I thought they may have been basically honest, but very misguided, yup, I was still very naive ! But this was blatant telling of whopping LIES by telling less than half the truth etc.
If they had "the truth" there would be no need to Lie through their teeth, no need to use loaded language, and no need to control the flow of information to the J.W Rank and File, but they always have, done all of that, and now it is in a much bigger way.
Why they fight against the Mountain of Evidence for Evolution by Natural Selection is because of their abysmally ignorant, and frankly very silly desire to take as much of the Bible as literal as they dare get away with.
Many Mainstream Christians maintain their faith, alongside an honest recognition of Scientific truths.
