Would the author say, "I am a ..." and end with any of the above? If so, they identify as that group.

That's what identity is, it's the set of things you consider yourself to be. "I am" and "I consider myself to be" are very simple clauses.

How big or small a part you decide to make your identities part of your personality is up to you, but like, they are still part of your identity.
