Parental Alienation Syndrome -PAS
"The Parental Alienation Syndrome is the deliberate attempt by one parent (and/or guardian/significant other) to distance his/her children from the other parent and in doing so, the parent engages the children in the process of destroying the affectional ties and familial bonds that once existed..."
Myself, and my son we are both experiencing the syndrome on our own skin. The perpetrator "the mother" is the alienating parent, the law does nothing to stop her, the society neither, she can still working, have friends, and be regarded as a normal person, while effectively she is a person with an evident mental disorder damaging life of others.
Eradicating PAS should be the concern of everyone, pretending it does exist is as bad as being affected by it.
