This is pointless nitpicking. I agree with the definition, but presenting it this way is not useful. None of them think menopause removes your sex, that is not what anyone means by “sex change”. Not us, not them. I’m not lending credence to anything.

“Sex” as it is usually defined is the ability to either be fertilized and bear children, or fertilize someone who can. To my knowledge, no human who has ever possessed either ability has ever possessed the other one. We are getting close to making one of those possible, though (in the MtF direction).

This is what they mean when they say sex can’t change, and this is what they think you’re telling them is possible.

The other things you mention, which may scientifically be part of sex, is not what anyone means in casual conversation. Those may change, voluntarily or not, yes. But the main thing people mean when they talk about someone’s “sex” cannot change yet, although it can be lost, or never obtained at all.

Gotta sell those climate un-changing pills somehow 🤷🏻‍♀️

Being trans myself, I will gladly tell you no one can change their biological sex yet (meaning, reproductive sex). I do hope science gets there though !

I don’t even think anyone can change their gender ! Some people’s gender changes on its own, but I’ve just always been a woman ; and most trans people are like me.

The thing we actually disagree about is whether someone’s gender and biological sex can be separate. But it’s just a scientific fact that they are.
