Done4good, thank you for mentioning their detailed and esoteric doctrine. Let's call it dogma, shall we?
You have isolated a HUGE problem for the WTBTS. In the past, their complicated type/anti-type dogma was "proof of Da Troof." What percentage of their doctrine exists due to Adventism/anti-typical schools of thought, 98%??
Take away the types/anti-types, which they are currently doing, and what's left? 2% of God and Jesus exist, the Kingdom, and be kind to others??? How are they any different than other sects without their types/anti-types?
Remember the Revelation Book? What percentage of that waste of time is considered "Da Troof?" LOL!! We can rest assured that the Revelation Book is in the same file as the Trinity brochure, File 13, destined for the shredder.
Perhaps the WTBTS wants to mainstream slowly, so as not to lose members needlessly? Perhaps they could no longer ignore the blatant falsehood of their types/anti-types? Perhaps they feared the sheeple would eventually find out?
Now, there seems to be a race against the clock. The WTBTS is racing to complete the new HQ, ( not going so well ), racing to gather money, and racing against their past deeds, and racing against the Information Age.
Is their advertising powerful enough to combat reality? With reality being in abundant supply, thanks to the passage of time and the Information Age, you wonder how long they can hold out. It seems like only an act of God could save them.
