Good that they attempt to justify their views and reasoning and feelings for leaving. I've seen so many former members write much better reasoned, thought out, and thoughtful documents than Martin Luther. Heck he wrote this and I would argue he was still dedicated to searching for truth:

If you have friends and family that genuinely believe that you have broken the chain and that there will be empty chairs in heaven because of you and you notice them acting more awkwardly around you because of that, then that is going to hurt and you are going to want them to understand why you don't believe that, even though usually they will only listen guardedly at best. And usually you'll quickly get moved from the friend list to the acquaintance list.
You start getting ghosted by people enough times, basically feeling like you're being convicted of thought crimes just for finding certain concepts less believable than others, then for certain types of personalities, you're going to get a hurt person who starts getting loud about their feelings. Maybe even in unhealthy ways. I've seen it happen and have had to talk them through how to handle their situation better.
Mostly cuz I'm good at capitulating to others, I've been able to maintain great relationships with my friends and family. It is a bit sad and telling that it always has to be that one way street though.
I just wish it wasn't so divisive. Like I could discuss any movie with my friend over the years and we could agree or disagree wholeheartedly on many things about any of the movies without any problem. Just keep talking it through. But if I ever brought up a certain movie that used to be watched in a certain building and super respectfully give the reasons for why I didn't find it believable or comforting, then suddenly there's immediate negative tension. No open dialogue like there is with everything else.
Just this past Sunday, I went to one of my best friends sons missionary homecomings. After the first hour, we went to their house for an open house lunch. Many of the wives there, not knowing about me, were going on and on about how sad it was that so and so's girlfriend was taking pictures on Instagram and obviously didn't have her garments on. They were seriously defaming this girl's character for about 5-10 minutes based on that.
This isn't a one-way street for why there are problems between the members and former members.
