Trans People and Cybermans (SPOILERS)
Before we begin, let me introduce myself. I'm Lilith, a trans girl and a Doctor Who fan, and if my English sounds a bit strange, it's because I'm learning the language and right now im using the Google Translate.
Context About Cybermans: (¡¡¡SPOILERS!!!)
The conversion to Cyber form usually involved painfully removing the brain from the individual's organic body and placing it in an armored suit. Once completed, the new Cyberman had a special implant that prevented them from feeling emotions. If this implant were removed or deactivated, the Cyberman would enter a traumatic state caused by the pain of the conversion.
This always resulted in an agonizing death due to emotional overload. End.
What I'm trying to say is that what kills a person is the emotional overload of being in a body that isn't their own, that doesn't feel like their own, and where their mind now resides. But as a trans person, I've felt these same emotions MANY times, so I think that because of this, perhaps trans people don't die when this happens and maybe they feel it's already "normal"—in so many quotes.
I apologize if this makes anyone uncomfortable or if my words aren't clear.
