You are mixing cause and effect with abandon.

Your understanding does not match the scientific evidence. One of the reasons being trans is not a mental illness is that cis people experience gender dysphoria all the time as well, like cis men when they're called girls, cis women with facial hair, or the revulsion many cis people experience when they even so much as think about the idea of taking hormones that don't align with their gender. To the extent that this is a "mental illness", the vast majority of people have it.

This is same low quality of reasoning as that daft research paper that tried to claim that most cis woman are autogynephiles.

I don't think the discomfort a typical cis man feels from say some locker room teasing about being a girl in any way compares to the mental struggles a trans person experiences. It seems weird (and minimizing the hardships of trans persons) to put that in the same bucket.

Idk what you’re talking about… I don’t look at depressed people like some evolutionary whatever whatever lol

If they want therapy I can pay for the therapy, if they want me to call them depresso mcfesso I can do that too idc. There’s no reason to be all high minded about stuff like this, man
