I am a trans woman. I am also a butch lesbian.
Despite what you may have heard, these are not contradicting identities.
A trans woman is a woman who was assigned male at birth by the medical industrial complex. This assignment is based entirely on the appearance of a phallus, specifically a phallus at least half-an-inch in length. That’s it.
A cis woman is a woman who was assigned female at birth by the medical industrial complex. This assignment is based entirely on the lack of a phallus (or a phallus less than half-an-inch, therefore acceptably small enough to be considered a clitoris). That’s it.
So forget whatever the hell you’ve heard about chromosomes, gonads, gametes, fertility, or anything else. (Chances are good you and your doctor have no idea what half of those are for you personally, anyway.) If you can accept that, it’s easy to accept how greatly variable everything else we take for granted about “sex” and “gender” is per individual.
