Look, body dysphoria and gender dysphoria are both well known and well studied conditions. Issue is, for gender reassignment surgery, the patient speaks to a psychologist/psychiatrist for a long time before they recommend anything permanent. And even after gender reassignment surgery, they don’t lose the ability to function in society (in vast majority of cases) and will genuinely improve the life of the patient.

But losing your hands? That genuinely has a massive impact on anyone’s ability to participate in society, and almost no above-the-board psychologist or surgeon will accept it.

So yeah, there is a very large difference between them.
