I had never heard Susie Green (or Keira Bell) speak until yesterday.
Two things struck me about SG.
First, that she is massively over-invested in her child. Unhealthily so.
Her child is her project. She has to defend the Mermaid position (and reject the findings of the court) because to do otherwise is to acknowledge what she had done to her child (and also what she has actively facilitated being done to other children). The guilt would be over-whelming were she to acknowledge what she is responsible for. She does not come across as very well balanced. She is a perfect example of why impartial, objective, evidence-based, multi-disciplinary services are required. Those with skin in the game, whether parents of children with dysphoria or trans-identifying adults should not be let within an asses' roar of these vulnerable children or their parents. In Ireland the problem is exemplified by TENI who are involved everywhere you turn, largely peopled by late-transitioning transwomen.
Second, which also suggests that she is not well-balanced: the repeated references to suicide as an inevitable outcome for children with dysphoria who are not facilitated in their hopes/wishes/demands (specifically in this case puberty blockers). The repeated references to this inevitability connects to her need to justify the appalling decisions she has made. Its function in arm-twisting frightened parents is another matter.
While I was horrified listening to her I also saw this persona built within a scaffolding which is slowly being pulled down around her. I can't say I felt sorry for her, but she is clearly someone who will need help to come to terms with what she has done. She is totally invested in this fantasy and needs it to continue for her own sense of self.
