Very interesting and well explained article. A MNetter who sadly hasn't been around for a while, said years ago something about when biological women put up a boundary or say no, it triggers 'mummy doesn't love us'. It's a thought I've come back to over and over again as so very astute in that primal rage you see and the inability to view those women as people or having any role or personhood other than meeting needs and demands of the asker.
It also links for me to a fierce argument I witnessed years ago between a group of adoptive mothers who had banded together for support in helping their very severely traumatised children. It was a group where dark humour and emotional support and open discussion of the stress and sometimes physical injury that the extreme needs of their children caused to them, where they were friends helping each other and not in that moment the calm, regulated, You Come First mum that they were every other moment of the day. An adult with severe childhood trauma tore into the group in utter fury that they should talk, even privately among themselves, about the stress and distress the behaviours caused, or even take time away from their children for this social contact. What the adult couldn't see but the mothers could, was that here was that traumatised toddler, screaming through this adult, you can be nobody but My Mum, you can do and think about nothing but me, you have no life or existence other than meeting MY needs, you can never be tired or angry or injured - those thoughts were too threatening and enraging to cope with.
I see plenty of that in the DIAF/barbed wire baseball bats. So much of this is toddler emotional level.
