Using the term "HRT" for cross sex hormones is inaccurate and gaslighting.
This is a very important point, SirVix.
Transgenderist terminology is a kind of Newspeak which has the overarching aim of linguistically erasing the reality of the sexed body. All the terms they use are directed towards this goal and it's worrying how uncritically they have been adopted by the media and, often, even by critics of the trans movement.
E.g., 'bottom surgery' for radical alteration of the genitals; 'top surgery' for double mastectomies; 'assigned female/male at birth', which implies one's reproductive sex is a random assignation rather than a material reality.
I pointed out in the Helen Webberley thread that the word 'transition' itself is a kind of Newspeak, because it's a metaphysical term that throws a veil over the physical interventions being done to the body (especially the bodies of children), and implies that human beings can cross over from one sex to another, when in fact we can't.
It's very important that we resist using this language, because it impedes the ability to describe and, worse, perceive what is actually going on here (as it is designed to do).
