Gender reassignment is a form of suicide.
You should elaborate on that so that it becomes an argument.
Is this suicide a metaphor ? How do they die?
When people commit suicide it's to escape some manifestation of pain. Children who are experiencing the natural pain of development, which is as equally painful as it is equally different for both genders, seek to kill their biological identity to transition to a different gender in the misguided assumption that it will be less painful.
