Hi nemail :)
I'm inactive. I've been out for about 4 years. Memorial 2004 was my last time in a hall.
The doctrine you bring up always confused me as well. Truthfully, I think it is nothing more than speculation... there isn't strong biblical support.
To answer your question, I think most of us here have lost a lot to the JW religion. Even though I'm not DF'd or DA'd I'm considered "bad association" and I'm ignored by most of our family and most of the people I grew up knowing. All but 3 of my friends. There is a huge, empty void in my past. Almost like it didn't really exist. My children lost grandparents, cousins, and aunties. I think you can credit scenarios like that, which are a dime a dozen here, for any bitterness you sense.
I personally don't seek out preaching to JW's because I believe that JW's should leave on their own terms when and if they want to. I don't believe it is right to stuff my opinions down anyone else's throat. So I come here and I talk to people who understand what it is like. I answer questions and relate to new ex-JW's who have sought this site out for support. I try to be kind and heartfelt to those who loose everything and everyone they have ever known. I am here to support others without condition, plainly.
So, I explained why I am here. You don't have to attack people for believing differently, nemail... I'll give you space to believe how you wish. I encourage you to do the same for me and the others on the board. If you want to talk rationally, ignore those who aren't having a rational discussion and discuss rationally with those who are. I would love to see more of you and engage in more conversations with you in the future.
