Can you explain this in more detail?
No, but I can paste you a link to an explanation I read recently...
"Yes, the definiition of medical condition includes mental illness, but not all medical conditions are mental illnesses. I am sure you understand that. To aid your understanding,, I refer you to the NHS guidlines, and I'll quote directly:
[https://www.nhs.uk/conditions/gender-dysphoria/ NHS Guidelines]
"This mismatch between sex and gender identity can lead to distressing and uncomfortable feelings that are called gender dysphoria. Gender dysphoria is a recognised medical condition, for which treatment is sometimes appropriate. It's not a mental illness."
You are more than welcome to argue with experts in the field of medicine, and assume that there is a massive conspiracy by the super-powerful trans lobby to corrupt the WHO, NHS, APA and other bodies, but that seems a little unlikley, certainly less likely than the other option. So which is it, massive world-wide conspiracy, or a reevalution?
As for the kind of medical condition it is:
"Gender dysphoria is a condition where a person experiences discomfort or distress because there's a mismatch between their biological sex and gender identity. It's sometimes known as gender incongruence."
