I hope more space is given to the voices of detransitioners. I think what Gill Smith has to say is really important too. She detransitioned from being a trans man.
If people want to medically transition, that's fine. But it's not going to be the solution to their problems. It's a treatment, not a changing of sex. So if you have such bad gender dysphoria that you find it intolerable to live in your body, you may (but not guaranteed) feel better if you have surgery or hormone treatment. However, it will not make you the opposite sex, and the problems you had before are likely to still be there. You will find it hard to fully pass for the opposite sex in most cases too, and there is a huge risk of side-effects from the treatment.
I think he is right that kids are being told that they can change sex easily when that is not true. If you are told that you can't change sex, only the most persistent children with real gender-dysphoria would continue to insist that they are the opposite sex. However, I reckon about 90% of the ones now referred to gender clinics would desist pretty easily.
The TWAW mantra is misleading and harmful. Trans women are trans women. In many situations, they can be treated the same as biological women- in a small number of situations they can't. Arguing the toss over who and what is a real woman is pointless and stupid. Focus on giving people the rights and protections they need- not feed them some bullshit that they then have to discover years later is not true.
