It's amazing what can be rationalized away when you spin religious poppycock, bullshit and outright lies as some kind of 'error' sanctioned by God.
For example, outspoken Watchtower critic and otherwise intelligent person Robert King, aka e-watchman, has given himself over to the whole idea that the JW religion is the true religion but that their false 1914 teaching is the literal fulfillment of the 'operation of error' spoken of in 2 Thess 2:11.
I suppose somebody has to run the fool's errand.
