I read about an even more disturbing delusional disorder a while ago, I'll see if I can find the link and post it later. Basically, you have able-bodied people who are convinced that they are disabled people mistakenly born into able bodies. They insist on using crutches and wheelchairs even though they don't need them, or in more extreme cases attempt to break their spines (or go overseas to get their lower spines severed) so that they can realize their "true identity" as paraplegics.
Again, this isn't so different from transsexuality.
Good Lord!!!
Cut the spine!!??
The myraid mental illnesses or defects of the brain are truly terrifying.
Read of one guy with a head injury that caused any food he looked at to be a horrid grayish color.
He committed suicide.
As for transgender, or whatever they are, they are no different than the people you speak of and are NOT FIT for military service.
Or much else.
