Yeah it seems like everyone here has a perception of Mormons that is significantly more hard line than reality. The shunning they’re talking about is not part of official church policy, and speaking as an ex Mormon myself, nobody in my life cut contact when I left because there’s no doctrine that says they should. Indeed, official doctrine is that you should support that person no matter what with the hopes that they come back into the fold. Jehovah’s Witnesses, by contrast, DO have official policy for how everyone should cut contact when someone is disfellowshipped.

I have a long laundry list of gripes with the LDS church, but this particular issue isn’t one of them (at least from a policy and doctrine perspective). I will note, however, that in times where I have seen this shunning happen, it’s rarely due to the person who left putting strain on their relationships. Instead, it’s typically due to religious fanaticism on an individual level from the LDS people in their lives. That’s unfortunately not unusual for religions, though, and I don’t think Mormons are unique here.
