That's possible. I was kicked out for legitimate reasons. It's only around my JW parents that I have any feelings of guilt about it though, because I now don't think I did anything wrong; sleeping with my husband before we got married, but obviously the JWs disagree. I think because I immediately joined this site I very quickly worked out that I really didn't. I know it was me who got me kicked out though.
Possibly, if I didn't have a place like this, and hadn't literally gorged on what was basically spiritual anarchy for me, it would have haunted me for the rest of my life. There's no way I could have worked through the grief of the loss of my family and friends without peers. It could have become an obsession; the need to justify myself, and bring them down.
