When a trans person changes their name, their previous name is their deadname now. If you aren't trans and you change your name, your previous name is not a deadname. If you are under the trans umbrella you can have a deadname.
Trans person: I changed my name
Ally: Okay!
Trans person: Please don't call me by my deadname anymore it makes me uncomfortable.
Ally: I'll try my best!
Referring to someone by the name they were born with instead of the name they chose for themselves after their mental breakdown.
"Hey James!"
"I've told you before, my name is Jamie now. Stop deadnaming me."
"Shut the fuck up James. It doesn't matter that you've had your dick removed. That doesn't make you a woman, it just makes you a man without a dick. Now put the fucking kettle on."
Deadnaming is the act of referring to a person by the name given by their parents, instead of by the name they chose for themselves later in life. It is considered by some to be an evil insult, and considered by others as a simple reference to who someone really is.
"If you grew up with Marilyn Monroe, and you call her Norma Jean, you are deadnaming her. Stop it, you evil monster!"
---------
"I demand that you call her Caitlyn from now on."
"But his name is Bruce. I would feel guilty if I ignored my conscience by purposely perpetuating a lie. I don't want to force myself to use a stage name as if it was real, or to pretend that someone is someone other than who they really are. If it upsets you when I use his real name or pronoun, then I will do my best to respect his feelings, and the feelings of others with your beliefs, by avoiding referring to him by EITHER name. And I will refer to him as "they/them" instead of "he/him"...but I refuse to refer to him as "she/her". I am doing my best to show respect to his feelings and yours, and I ask that you also respect MY feelings by not trying to force me to lie, and that you please stop trying to police my thoughts and beliefs with threats of cancellation."
