GL Tirebiter, as a non-believer, did you ever discuss with your ex that you found his behaviour peculiar?
No, it was difficult to discuss anything related to the WTBTS with her, essentially impossible. In her eyes any disagreement merely showed that I "hate the Witnesses."
Separating your regard for someone as a person from your opinion of their behavior was something she did not fathom. I think that has much to do with shunning: if a person fails in some way, they must be A Bad Person. Never mind that "all have sinned, and come short of the glory of God" (Romans 3:23).
