This is a neat rhetorical trick, but it doesn’t work.
Affirming someone’s actual sex is not “converting” them to anything. Sex is not a belief system, a sexuality, a religion, a political identity or a lifestyle choice. It is the material reality the person already has. You cannot convert someone into being the sex they already are.
What you are doing is smuggling in the assumption that any therapeutic approach which does not affirm a claimed gender identity must therefore be “conversion therapy”. But that is precisely the contested point. It is not an argument. It is just a demand that everyone accept the gender-affirming model as the only morally permitted model.
A therapist saying, “I accept that you feel this distress, let’s understand it carefully before drawing conclusions,” is not conversion therapy. It is therapy.
A therapist saying, “Your distress proves your gender identity is true and everyone else must affirm it,” is not neutral care. It is an ideological commitment dressed up as clinical compassion.
The phrase “sex-affirming” may or may not be the best branding. I’m not especially attached to it. But the idea that acknowledging someone’s actual sex is “conversion” is absurd. Conversion requires changing someone from one thing into another. Recognising reality is not conversion. Helping someone live with their own body is not conversion. Refusing to immediately validate a self-diagnosis is not conversion.
What is actually gobsmacking is the confidence with which you treat your own premise as proven. You haven’t shown that anything here is conversion therapy. You’ve just declared it, then insulted everyone who doesn’t accept your declaration.
