Violet, I think that in asking this question it leads to more questions and the need to do more research.
The first question that came to m mind is "are there any other denominations or sects that treat those who choose to leave with utter contempt, to the point of thinking of them as walking dead?"
I am a lapsed Catholic, yet all of my Catholic relatives treat me no differently than they do one another. Occasionally my Aunt reminds me that its never too late to go back, but she always says it and then drops the matter.
I think the high emotion you see on this board and other like it comes from the utter rejection, contempt, and disgust displayed towards those who have done nothing more heinous than find another way to worship their God, or another way to understand their purpose in the universe. Yet they are treated like lepers, like murderers or thieves by people who falsely claimed to love them at one time.
This sort of treatment of others makes the WTS members Pharisees, not the harbingers of truth. Remember from your bible studies, the Pharisees had so much arrogance because they thought that they were God's chosen also. yet Christ despised them and made fools of them at every opportunity. He showed more hatred and virulent resistance to them than to murderers, thieves, etc.
Please think about this.
Unless you have personally experienced the rejection that some members of this community of apostates have experienced, I do not see how you can judge the WTS, which has caused their pain, as the truth.
