[Merail] Mr Menno's recent video about Davey Wavey with Haskell (?) as a TM includes Twitter screenshots, iirc, of TM arguing that no surgery nor hormones should be necessary to be recognised as a TM. This one is about surgery.
I'm sure there are more about 'neither surgery nor hormones' which is the more extreme TM version of Veronica Ivy's position, to some extent. [/merail]
But, extending that, if it's sufficient for someone to assert that they are a TW without any medical or surgical intervention, then there may well be a cohort of entirely healthy male bodies to put themselves forward as clinical trial participants on the absolute understanding that they might or might not embark on medical or surgical interventions later.
No. I don't believe this. But, this is where our legal fictions and the compelled societal acceptance of them may lead us.
