I was born and raised as a Jehovah's Witness and spent some 30 years in the organization. I studied their publications for some 20 years. I researched the key doctrines frontwards and backwards. I spent countless hours pouring over Watchtower publications in addition to many Bible translations, commentaries, and other books by Biblical scholars (real scholars, not JW pseudo-scholars).
So, I find it amusing that Watchtower apologists would admonish people like me to be "open minded" about the very Watchtower teachings that I have discovered to be false.
I have heard of accounts of the gold rush of the late 1800's where excited prospectors took loads of gold flakes into the exchanges only to be informed that it was fool's gold. Upon hearing this, the prospectors became angry; insisting that the exchange merchants were wrong and that their equipment must be flawed. They insisted that what they had really was gold, and that the merchants just couldn't see it. They clearly had an emotional investment in believing that what they had found was the real thing. It was all they had left. This is very similar to those who have spent a lifetime invested in a religious organization.
This reminds me of the Watchtower with all of it's surrogates, apologists, and clingers-on. They just cannot let go of the idea that Russell hit "gold" with his Watchtower enterprise; insisting that it is everyone else who is wrong, and who cannot see the "spiritual gold mine" of the Watchtower. It is very inconvenient for them that some people choose to exercise incredulity in spotting the genuine from the bogus.
