Not really. Defining someone by a small portion of the whole person is just how language works. If we had to make an exhaustive list of who and what someone is in order to talk about them, every conversation would read like the formal introductions in an Earth’s Children book and nobody would ever get anything said.
"My husband, son of Soandso and Thusandsuch, brother of MissThang, nephew of the Whosits, cousin to Thing 1 and Thing 2, friend of Dooflitchy, physician, musician, volunteer DJ, NPR donor and listener, cook, gardener, Wildcats fan, and general smartass, and I, daughter of What’shisface and Whoever, sister of Buttface, aunt to CutiePie, niece of the Thingumbobs, friend of XYZ, medical assistant, quilter, crocheter, gardener, keeper of animals, and possessor of the Rack of Doom, are thinking about going to Cancun.
Nobody’s going to talk like that, and if they did, nobody would listen.
Sometimes we’re defined by positive or neutral slices of who we are, and sometimes by negative ones, depending on what part of us is most relevant to the current discussion/situation. If it matters most that you’re my husband/mother/coworker because we’re having a cookout, I’ll use that narrow definition for you. If it matters most that you’re an addict because you’re robbing my grandparents to buy drugs, guess what I’m going to call you?
