I would say that causing someone pain doesn't make a person abusive, unless they have a history of being abusive. Unless they used and abused then discarded you.
Some of the stories on here appear to be exactly that scenario.
I think it's probably better to simply be sympathetic to real genuine emotional distress and remember that estrangement often causes pain for both parties and both deserve to be heard
On here we usually only hear one parties experience of estrangement or fear of estrangement. We hear their viewpoint, how they have experienced it. Some feel they have been abused. Some do not. Listening to , empathising, giving constructive critical advice can be a helpful response for that person. It doesn't mean that the fact that estrangement causes pain and distress to both parties has been forgotten
A strength if this estrangement forum is when estranged EPs get constructive, empathetic and thoughtful advice including from estranged AC, who are able to objectively consider the perspective of the poster despite their own negative parental experiences. And also when EAC who post about their distress get constructive, empathetic and thoughtful advice from other posters, including EPs who are also able to objectively consider the perspective of the poster despite, their own negative AC experiences
In both cases there is clearly a recognition of pain for all/both parties, in different circumstances
