I agree completely.
It was more that I was trying (quite possibly badly) to talk about consent, and if society is massively transphobic according to the sorts of people who are pushing for this PB trial to go ahead, then surely the people who are pushing for this PB trial to go ahead can only get informed consent after telling the potential child participants of the constant transphobia that they will face.
If the TRAs pushing this trial are not doing this, then it is yet another example of their hypocrisy and dishonesty.
Either society is not transphobic, and they need to stop with the accusations that we are, or society is transphobic and they need to ensure that PB trial participants who are at risk of a life of being on the receiving end of transphobic bullying know what they are letting themselves into.
I don't think this is quite the same argument as the argument about the law. Clearly for informed consent all "trans kids" would need to be made to fully understand that most people believe that the sex based rights of women and LGB trump the cross-sex privileges of trans people, and that the only way that they can "live as the opposite sex" is to play at dress up, and not to use opposite sex facilities.
I'm trying to think of another example. Imagine you have severely damaged legs, which just about work but leave you moving around slowly and in significant pain. If you live in a very flat, modern country with amazing laws that ensure wheelchair bound people can get wherever they want, whenever they want, then amputation is probably your best option. If you live in a mountainous country with a history of associating physical disabilities with mental disabilities, and total disrespect for both, then maybe you're better off struggling up steps in pain. It would be totally wrong to have a conversation about consent for amputations that did not bring up the way the country is not set up (physically or in terms of attitudes) for those in wheelchairs.
