I understand both sides of this. I completely understand "without the WT none of us would know Jehovah", but is that really true? Jesus said if men did not speak about Jehovah the rocks would. The credit lies with Jehovah. However, it is true that Jehovah has used the WT, I'm just not sure if it's true anymore.
I believe what you mentioned about being wrongfully DF'd has happened often and I think one big reason is this attitude "elders are appointed by holy spirit." Which is a complete misapplication of the Bible. The appointment of Elders is done by the direction of the Bible, but the decision is made by imperfect men, as if that even mattered. The perfect angels and Satan still rebelled. My point is, it's not just "prophecy", much of the WT is used to bludgeon the sheep with the judgemental attitude of the WT. The Watchtower is more and more tainted with the WT attitude. I personally do not see how you can separate the two, the truth from the lie. And this has been going on for decades, it's just gotten worse IMO.
20 or so years ago an Elder when asked why they were going to "reprove someone" asked the person, "are you questioning spirit appointed brothers?" Meanwhile his young teenage son, and started a Gay relationship with someone from another state online and left soon after and moved in with him. (The earliest beginnings of the internet.) The hypocrisy is palpable indeed. I'm not saying this Elder knew about this, what I am talking about is this inexcusable arrogance,and complete lack of self awareness and empathy that has no place in the "House of Jehovah" and especially, I say again especially with the "shepherds." And those same "sheperds" are the ones writing the Watchtower!
But, your attitude is certainly admirable, and commendable and I would also say an example as well.
