I heard this term this morning and had to look it up. Dead-Naming. Evidently, that is the practice of, when dealing with trans people, of using the name they were born with instead of the name they prefer. For edample.
Lets say you know a guy named Joe. Went to high school with him. Joe was always a little bit standoff-ish, but other wise okay. Ten years later you run into Joe on the street, and he says his name is Sally. If you keep calling him Joe, you are dead-naming.
So, this leads to problems. Did Joe go through the process of legally changing his name? Or is he just stage-acting? How seriously should we take Joe at his word. Or did I just misgender him? Oops, did it again. Did Joe get a boob job, or is he still wearing a beard? If both, he can get work in a circus.
When I was a single man, both as a young adult and later as a mature adult, I had one iron-clad rule for dating. I would never date a woman who could display a better moustache than mine. And I have a very poor moustache. I'm just sayin'.
