when will people please stop using the “being trans is a disease so you can’t be trans unless you have medically diagnosed dysphoria” thing in discussions of being trans / nonbinary / etc. ?

because science and medicine have historically been used to oppress people (i.e. drapetomania, used to justify eugenics of disabled people, PoC, etc.)

so an extreme, unquestioning dependence on a discipline that is ever-changing and developing with a large and extensive history in the use of moral justification for oppression is just

1) wrong, and

2) oppressive considering the history behind many facets of it
