@ GabrielleNelson Trans women believe that they are women and are offended by people saying that they aren't, hence why some will find the hoodie offensive. If the statement was purely a biological fact and had no political intent behind it, there would be no need or desire to put it on a hoodie. I don't really think that does baffle you - at least it shouldn't.
What baffles me is how the assertion that TWAW (with the occasional afterthought statement TMAM) has gained such traction in such a short time. Did old school transsexuals believe they had genuinely changed sex? I doubt it. From what I've read they had spent years having psychiatric treatment and a condition of getting the surgery was to accept that they were suffering from the psychological condition of gender dysphoria or whatever the label was then. Dysphoria also was and is a condition of getting a GRC - if you don't have the dysphoria diagnosis from a psychiatrist, you don't get a GRC.
But here we are now in a position where a small but extremely vocal and influential minority of the population has managed to get public policy changed amazingly fast right across the English-speaking world (the more affluent countries, anyway) to a point where it's become controversial to say that biological sex exists, it's binary and it's unchangeable because sex is fixed at conception and no matter how much hormone treatment and surgery a person has later on, at the chromosomal level they will remain the sex they were born as.
Transwomen are not women. Transwomen are biologically male. For a variety of reasons they prefer to present to the world in accordance with the stereotypes generally applied to females in their culture. That's their right, but it doesn't change the underlying biological reality.
In all other cases, we expect people to accept the physical reality of the world they live in and their own bodies, and where they don't/can't we see that there is something wrong that needs to be sorted out.
If a teenager with an eating disorder insisted on being accepted as fat even if everyone could see she was actually painfully thin, no one would hesitate to say she was ill and needed help to get over this delusion.
If a patient tells a GP that they have become convinced their left eye doesn't belong to them and needs to be removed, the GP should not be arranging a referral for surgery. This is a case for psychiatric/psychological help.
If a psychiatric inpatient is convinced he can fly, the staff don't open the windows and help him out onto the window ledge.
But if a little boy who prefers dressing up to playing with toy soldiers becomes convinced that means he should really be a girl it's become acceptable in some circles to say to him 'yes, you were born in the wrong body and when you are older you can have an operation to make you into a girl'.
And if a teenager who has experienced abuse has come to hate her own body and wants to change it so that nobody treats her that way again, doctors are facilitating that instead of helping her to come to terms with what's been done to her and equipping her with the personal resilience to get through puberty and cope with adult life.
And if a middle-aged man who has built a career without having to worry about maternity leave or other caring responsibilities, who has married and had children, decides to go public and say that all his life he has secretly felt compelled to dress up in women's clothes and now he wants to do it full-time, the rest of us are now expected to do a bit of 1984ish reprogramming of our memory banks and treat this individual as a woman even though we know for sure that he isn't, and we're also expected to put out of our minds the knowledge that for many such men this is a sexual fetish.
This is what baffles me.
