Apologies if this has already been discussed.
I have often wondered why the TRA faction so vehemently disagrees with JKRs statements of fact around the reality of the semester, as you need to respect the existence of sex in order to transition from one to the other.
This article, Harry Potter and the Reverse Voltaire by Mary Leng goes some way to explaining why. medium.com/@mary.leng/harry-potter-and-the-reverse-voltaire-4c7f3a07241
Its fairly lengthy but well worth it.
It concludes, while there might well be some good reasons to adopt a concept of ‘woman’ according to which trans women are women, we cannot do so without also retaining the separate concept of ‘female’ and without retaining the ability to talk about — and fight against — the forms of oppression faced by female people under patriarchy. This is not to say that we don’t think that trans people exist, or that they matter, and it is not to say that we don’t believe that trans people also suffer harms under patriarchy. We do see all this. And we would like to work together to dismantle a system that harms us all. But we cannot do this if we are not permitted to acknowledge what is distinctive about the way each group (females and trans people) are harmed by patriarchy. If we are denied the language and resources to recognise, record, and respond to the facts of female oppression, we will not be able to ameliorate these harms.
(And the postscript and post-postscript are fascinating too)
