Half banana - "Then they must think we are a serious threat to their existence."
The way they've been behaving, that's super hard to argue with.

And that, IMO, is the real telling point.
They wouldn't be acting as though the Org's survival was at risk unless they truly did believe (subconsciously or otherwise) that it was.
That fact - in and of itself - suggests that on some level, the leadership knows that the Watchtower Society is Wrong...
...because if they were Right (and therefore had God's backing) they'd have no valid reason to act increasingly defensive of the Org's survival.

You shouldn't need to use legal finagling and intimidation to stay in the game if you possess the actual moral high ground...
...therefore, the fact that they do use those tactics indicates that they don't have the moral high ground...
...i.e. they don't have The Truth.
