I think that prior to the Watchtower being published Pastor Russell believed that 1914 would be the end of the gentile times. I find that I cannot prove that from God's viewpoint this did not happen
I believe the Witnesses view 1919 as the birth of the nation and we find there are millions of JW since then and the anointed going to heaven from that time forward, I cannot prove hasn't happened.
We do find them claiming to be anointed and commissioned to engage in the witness work of the events of 1914 which they do on a worldwide scale supposedly in fulfilment of Matthew 24:14, I believe.
No doubt many realize that the king isn't wearing any clothes, but they dare not say one negative word because they would rather believe in a lie and stay in the congregation rather than believe the truth and be set free.
So although like you I was there in 1975 and our family had simplified our lives and I was pioneering and today I no longer attend the Kingdom Hall or engage in the work. I feel I am no longer convinced of the message we preached but do not feel that I can comment on whether they are anointed or were commissioned in 1919 I therefore can understand that some maybe convinced of this even though they recognize some errors of the past.
