The fact that parents will die rather than take blood or let their child die shows you what the power of the organisation has over people...
The JW's who are leaving are the ones that examine everything whilst those who stay in are the ones who let the society think for them...thus it seems the majority will accept any change the society make...
The GB know they have this power...in times gone by the GB tried to give evidence and proof for their changes but now they don't bother as they know the majority just accept "they are the Faithful and Discreet Slave Class" and just lap it up...the fact they said "evidently what Jesus meant was an overlapping generation"..."evidently"? Where is the evidence? They don'y need it...
So...I can see major changes to 144,000 and 1914 coming...and it will not make one difference to most of those who don't bother to check what they believe...
