" For one thing, why so many unsound members " ? The apple doesn't fall far from the tree- the WT Society leaders are unsound so they produce unsound members. Pretty simple.
" What kind of religion produces thousands of people like this " ? A religion that PRETENDS to be a religion but in reality is a real estate/ marketing company giving out false hopes through mind control masquerading as a religion for financial purposes.
" How does the Church know that these people have a mistaken view and what causes it"? WT leaders really don't know anything in reality. All they know is their false teachings which manipulate rank & file JW's to THINK that more of them have a " heavenly calling. " WT Society HAD to open up the heavenly calling to more JW's for basically selfish reasons- more of their Governing Body leaders were dying off being replaced by younger men of age 50 + who previously did not claim to have a hope of heavenly life. So about in 2005 WT Society TOTALLY changed their views of the heavenly calling being closed up in the early 1930's and opened it back up on their own to accommodate their Governing Body members having the alleged " heavenly calling " . It wasn't set up by God or any inspiration- just a random decision made by leaders of a cult to push their agenda of " end times " and control.
" Is this a professional opinion, and if not, how could they even say such a thing about people " ? No, WT Society leaders are NOT professional in judging people. They DO make a profession out of controlling 8 million Jehovah's Witnesses through mind control- intentionally - in order to get control of JW's finances, lives, friendships, and any other material asset that can be used by WT leaders. They do this with persuasive tactics using FEAR and GUILT to manipulate JW's into thinking WT leaders are special and appointed by God- which is a lie, they are NOT appointed by God - they are leaders of an evil cult bent on controlling people and breaking up families. You ask HOW they can say what they do ? Easy- they're leaders of a mind control cult- they can say anything they want in a deceptive way in order to get rank & file JW's to obey them and do what they want. Think of the cult leader " Neegan " on the current " Walking Dead " episodes. Perhaps not with that much violence- but the psychological manipulation is exactly the same. Use FEAR and GUILT to control people and you've got them under your thumb. That is what WT leaders are good at doing- controlling people's lives. Period
