Welcome BackSlider ! Glad to see you have woken up to what the WT/JW religion really is, i.e a Publishing and Real Estate Company posing as a religion, and glad to have you posting here too.
I too think they have painted themselves in to a corner with regard to the 1914 doctrine, and the 1919 choosing, without the latter they have no authority, no voice, of course.
Over recent years we have seen a hiding of how 1914 is arrived at, it is only spoken of as a "given", same with the 1919 choosing, the reasoning behind that is so vague, and so well buried in WT literature, that the only way a JW could learn what it was would be to join here and ask an expert like "Cedars".
Most JW's are actually hard pushed to put the 1914 doctrine in an intelligible way, 99.9% of JW's cannot even get close to the 1919 choosing, they just brush it off as "proved as far as they are concerned", in other words they have never looked at the teaching.
And they have the barefaced cheek to go to people's door and tell them they should examine their religion because JW's have the "truth" !
