Because even though most of us here aren't JW's anymore and are working on moving on with our lives, trying to make the best of our lives, etc - it will never take away the fact that a great many of us here:
- wasted a childhood, early adulthood, and/or other significant important time in your life on a cult
- lost our entire families for having the balls to think outside the box
- were mistreated and/or thrown to the curb like a piece of garbage by "god's loving organization" once we stepped out of line
- had memorable, most likely unpleasant, experiences of some sort that impacted our lives courtesy of the borganization
I know personally, although I'm completely mentally free of their poison for years now, that it still makes me angry. It still hurts to lose a wife and a family (although in hindsight, they were shitty people) just because you don't want to devote your life to an invisible ancient Hebrew imaginary friend. Being in my early 30's, it's still fresh in my mind that just over 2 decades of my life from birth onward were a complete waste of time and arguable detrimentel to my life in many ways.
Wasting 20+ years on a lie that your parents, other family, and other JW's burned into your head stings the nostrils. It is not something that fades quickly.
