As you're probably aware, the WHO had to remove gender dysphoria as a mental illness in 2017 under political pressure from trans activists who didn't want it categorised in such a way. Similarly, the dsm 5 was changed under a similar climate of political pressure where gender dysphoria was introduced and it became about aligning the body with the identity rather than anything to do with a psychological disorder. It's one of those things though that everyone knows to be true and yet refuse to speak the truth for fear of being labelled.
