This is exactly why the trans community should reject the language of identity—especially gender identity. It frames who we are as a personal choice rather than a fact of our existence. Identity suggests something assumed or adopted, not something innate. But my sex—and therefore my gender—is female. That's not an identity. It's reality.
My sex is an inherent part of who I am—not some nebulous third concept like "gender identity," a term that, in practice, is applied almost exclusively to transgender people, as if our existence must be qualified or explained away.
