Moshe,
Yes, they would have to act as a group. But they do not, they cannot. Let me be frank, how many brothers and sisters who have left their Jehovah's Witness faith have remained believers in God's existence? Does anyone here have a number for this? Now, let me ask, what incentive do I, or other Witnesses who question the leadership, have to encourage our friends to leave their faith? Can we honestly hope that all our friends who leave will remain believers in God?
You ask that we kill our own, I realize you do not think of it that way, but for us that is the reality. No, we will not kill our own. We will sooner work against all who vilify the Watchtower than kill our own. Yes, the Watchtower that insists at times in killing us, ourselves. I take the example of the U.S. again, Americans may disagree with their leadership and even hate what they do, but few will leave and few will take up arms against what they believe is a government based on good principles. We feel likewise with respect to the Witness faith.
Did you hear what this old man said? This old man who took the name, Damn The Watchtower? I would never encourage my brother or sister to leave their faith because, in truth, what is outside of the our faith is at the very least unknown and at most may lead to unbelief in God's existence.
Do not think we are all idiots led by idiots. No, we are lovers of God who at times are in shame over our leadership but we still love our God.
Thank you, Moshe, for your kind words.
