the idea that this person would use the language of consent to claim that their mother forced them to go through a naturally occurring development phase is really just the latest in a long line of astonishing appropriation
I think it's worse than that. I think it builds on the idea that children can give consent. And if children can consent to sterilisation when still pre-pubescent, what else can they consent to?
It is, yet again, opening a door that should not be opened, whether the person understands this is what they are doing or not. It is, yet again, a coach and horses attempting to drive through safeguarding.
