>"This is my friend, Jay. I met them at work. They are a talented artist."Jay here is known. This is not a case of being possessive. It's an entirely different type. All that is happening is they are replacing a functional pronoun for one that makes them feel special because they don't wish to conform to a gender roll. Even in cases where the gender identity of a person isn't known that isn't how you use they or them.
>"Hey Bill. Todd had a kid right? How is it doing?"You wouldn't use they or them as a pronouns to identify the child, you use identifying descriptors like "Child, kid, it, or the baby. Same thing here with a response.
>"It's doing alright." You wouldn't use they or them here as it implies multiple people. The first guy didn't ask about anyone else but the child. You can't use they or them because it lumps into a group overriding the point of it being a singular assessment.
