A common experience that is talked about in a lot of groups where family estrangement is discussed is the one of being labeled with a pathological condition by the person from whom you are estranged. With their only qualifications being that they are related to you and that they knew you once upon a time, they diagnose you as being something that is generally thought to be pretty horrible. While there are people who do deserve those labels, there are a whole lot of people who do not.
I am not going to argue with anyone about the fact that there are people who are not objective about their relatives and who don't know what they are talking about when they malign them. It happens far too often. When the person maligned does not deserve what is being said about them, this behavior is abusive.
I found a very good discussion on this experience that I am linking to here:
