Identifying as, and actually being, are too very different things. They can "identify" as a rubber ducky, and it still wouldn't make it so.
But in the end. That has nothing to do with me not being able to see... what you see.
My literal thinking won't allow me to look at a flower and call it a duck. I see a female, I call it female. It is like humans think that if one day someone decided that a ham sandwich is now called a doorstop. We should all follow this "logic".
Edit: I identify as autistic, because I actually am autistic. Big difference.
