@theleftistlawyer that's just superfluous. It's like every human saying that they're a human. Imagine if you introduced yourself as Hi, I'm [name], [he/she/it], a human. If someone mistook me as a girl I'd correct them and move on, the beard makes it hard tho.
At work we all put pronouns in our profiles, and that's perfect, removes any doubt, especially in online meetings.
