It is also a term it seems to me, that is widely used by parents whose adult children have gone no contact with them and not because their adult children are in every case, protecting themselves.
It's a question of semantics. As you have said "some articles also misuse it which in IMO is wrong"; that is your opinion and one I disagree with.
I find your posts somewhat confusing. You say no contact with your mother is not something you want, but parents whose adult children have gone no contact with them, is not something they want. So for me, no contact is valid in both cases.
I wonder why you say that some people won't care "what it means to me (you) or others like me (you)". That suggests there's an arbitrary use of the term no contact by parents whose children have made that decision, and they don't care how that may impact on those in your situation.
They say their adult child have gone no contact because that is their experience. There's the danger that they may be made to feel that there are some who don't care about their experience.
Your final paragraph seems to suggest that anyone not agreeing with you on this which includes me, "think that EAC who have gone no contact with abusive parents aren't justified or aren't telling the truth".
I have certainly not said or even suggested that that is what I think, because I don't, and I haven't seen anyone else suggest or say so either.
