Thanks @Thingybob I was interested in thinking through the rationale for the support of the experiment, it wasn't just a lone evil man, he had widespread academic interest and support. Why?
Surely that's an important question? What are the situations or rationales which occur where harm to children is supported or overlooked?
I've been thinking about it more and Money's initial position was: there is sex but your social role or 'gender identity' is just socially constructed stereotypes. This is the position GC feminists still currently take. He believed gender was a social construct, which allowed for the theory at least that all gendered behaviour and roles can be socially shaped through reinforcement.
That theory was the rationale for this experiment. Girl gendered behaviour or stereotypes could in theory be socially reinforced on a boy who didn't know he was a boy.
So they tried it.
Many people hoping and wanting it to be successful.
If it had worked and David had been successfully shaped into stereotypical girl behaviour I wonder whether GC feminists would be citing it as evidence for the theory? (Whilst of course noting the now agreed horrifically unethical nature of the experiment).
I think the fact it didn't work allowed it to be used to create Gender Ideology instead suggesting an innate gender identity which is usually in line with your sex, like David and cis people, but can be out of line, which is what Trans people are.
This isn't what Money was intending to prove, he was trying to prove gender is a social construct. The failure however allowed gender ideology to take hold.
Either way whatever rationale or outcome everyone now agrees this was an abusive man and a hideous experiment, but I do think who supported it, who wanted it to work and who has utilised the fact it failed is worth reflecting on.
I'm surprised anyone interested in where we currently are with children being used & harmed to prove an ideology isn't interested in some analysis of this, and I find the outright rejection & indignation at such questions a sad indication of people more interested in protecting their ideology than scrutiny.
