"Being gender identities, New York City residents can simply choose their identity, without ever having to show proof of gender. So I’m guessing a person could even choose a separate gender for each day of a 31-day month, and that would be… legal. Apparently, you can be fined upto $ 250,000 for failure to use and/or recognize an employee’s, tenant’s, customer’s, or client’s preferred name, pronoun and title (e.g., Ms./Mrs.) regardless of the individual’s sex assigned at birth, anatomy, gender, medical history, appearance, or the sex indicated on the individual’s identification." - Trove 42
