Listen to me… Data would be so fascinated (DELIGHTED) with the nonbinary identity.
While some of his programming does rely on binary functions, his personality is open, organic, always developing. He has learned from men, women, and others. He has adapted their traits into his personality, and never feels quite justified in referring to himself as a man. He is the sum of a spectrum of identities and experiences.
He understands ‘binary’ as something unique to computers. Not to sentient life.
Discovering this identity is another step on his journey to humanity.
