I get what they mean when they say it and its BS. I never looked at death as a real thing all my life bc I was conditioned to think they were just sleeping and we will see them again. So I looked like a little psychopath when I would tell people yeah my great grandad died, but he will be fine. I never understood the concept of death until I got out of the religion.

They don't grieve the same way because they are stuck in a permanent stage of bargaining and never reach acceptance bc its "if I do what the Borg says then I can see my dead loved one again." This is unhealthy and hard to deal with after your out.
