Is There Value to the Concept of Race?

There is a character (Taylor) in the Showtime TV series Billions who wishes to be referred to by others with the pronoun “they”. This person is brilliant and successful, and they do not wish to be painted into a particular gender box. And thus the focus on pronouns.

I like and respect the character in the show (at least for the first two seasons), but I found their wishing to use the term “they” to be kind of silly. As someone who grew up in the 80s, for me the pronoun “they” indicates “more than one”, so to refer to a singular person with “they” seems incorrect…
