Does anyone think that they may ever change/retire the 1919 date? If 1914 is negotiable, then 1919, which is arguably attached to 1914, is also theoretically in play.
The trouble with 1919 is that it is fairly foundational; without it, they can't claim to be special.
But, if not in so many words, they're already saying that they're not special ("flawed human beings", "mistakes have been made"). But they still want the R&F to treat them as God's earthly channel, while they want governments to believe that they have no influence over JWs.
They've painted themselves into a bit of a corner.
