I have seen EP ask other EP questions that would prompt them to ponder whether they could have done something differently. But I think there are reasons why it might not happen:
Society at large holds parents, and in general mothers, responsible for almost everything that goes wrong for children. I'm not saying parents aren't the biggest influence, but there are others. And research I've read on more recent psychological research suggests that some of these other influences can be significant. And yet, as a mum, if anything goes wrong in your child's life you can feel responsible. You probably question what you could have done to prevent it or done better. Further to that women are generally held to higher account or responsibility than men for many things. Would people discuss what a man was wearing if he got raped for example? So I think women don't want to 'hold to account' other women whom they know will have been judged, and judged themselves harshly many times.
And I do hope that nobody would 'hold to account' any EC who have gone NC. Their reasons are theirs, and if they want to share them hopefully they will be supported. If the OP had posted, 'does anyone think I was being abusive by going NC with my parents' I would be astonished if anyone could say yes you were. But if someone opens up a topic as a general discussion, it will bring up all kinds of thoughts.
Now it may be there are some that should be pushed to look at their own behaviour. But, firstly, judging the whole picture by a few snippets can by inaccurate. Secondly, telling someone, 'do you think you could have done this better?' when they have already lost contact isn't going to help them fix it. When there are chances of reconcilliation and someone says they are meeting with family they were previously estranged from, then hopefully advice will be as objective as possible. People often suggest expert reading or therapy - I don't think those sources will just say, 'yes yes you are always right' - but it's a gentle way to get people to get objective input.
Sometimes this feels awfully like 'taking sides'. But perhaps we need to bear in mind that it is natural to feel some empathy for others that are suffering in the same way we are. That doesn't mean we shouldn't be honest with them though.
I'm afraid some of the later things in this thread refer back to things I haven't seen. But I think if we can talk respectfully and clear up misunderstandings when they arise we can all learn and support from one another. I certainly wouldn't want anyone to think they had to tow any specific line.
Starblaze I totally see how you interpreted the comment we were discussing. And that's how I would expect you to interpret it, that is how it would be seen from your position. A position I relate to. I was merely trying to point out that it can be seen from other view points. As well, not instead. Some of which I also relate to. When people bang on about blanket statements they are not dictating rules (if that's what the rule thing is about?) or saying what the person is saying is wrong they are merely pointing out that blanket statements are usually interpreted differently to statements worded more specifically, and this can hamper communication and cause discord in a discussion needlessly. If anyone doesn't know why this keeps getting mentioned please do google why blanket statements cause arguments to check it out. And if I'm preaching to better communicators than me, sorry, I'm doing my best.
I totally support everything else you said in that post and the last post starblaze and the way you worded it was really helpful. And even as I'm writing that I'm thinking, 'oh heck I hope that doesn't sound patronising or like I'm a self-appointed expert or....' See so many pitfalls in communicating. Especially on forums.
