Shunning tends to comes in degrees. I don't think I ever shunned anyone hard, however I do know that I made the awful mistake of ignoring friends that left, which was more than bad enough. It never sat well with me, but knowing that does not make me feel any better about it, nor should it.
I tried reaching out to some of those folks after I left, and I can tell you the relationships were never the same. I deserved that.
Funny thing was, when I left, being shunned didn't bother me all that much. It took the loss of a very personally meaningful friend years later to experience that kind of immense pain. It was then when I finally understood why I stayed away all those years after leaving, and also how incredibly hurtful shunning is. Talk about karma.
I tell myself now that they cannot help it for the most part, just like I could not when I believed. Evil fucking cult. No one should ever be made to dehumanize themselves to that point.
