Family’s protection of their own feelings of guilt onto the scapegoat is a psychological defense mechanism.
If the scapegoat becomes too insistent about expressing his / her point of view.
The rest of the family may cut him / her off from it entirely, thus totally isolating him / her.
You can recognize survivors of abuse by their courage.
Children of toxic parents could have PhDs in justifying why their parents treated them so badly.
Scapegoated children and adults may suffer from chronic insecurity in relationships.
This is very common in dysfunctional / toxic family, or even at toxic work environment.
Abuser choose ignore or pretend victims are not exist, at the same time, they may over-empathize another person’s behavior, praise and adore them with no sense.
The aim is to downgrade the status of victim, make them know that they are not valuable / worthy to the abuser. This can damage target’s self-esteem / confidence seriously as they may feel / think they are useless.
