I had dental treatment on the NHS and it was £20 or so charged as a flat fee (so irrespective of what the actual problem was/what needed doing), definitely not £70? If it’s gone up that much since then, that’s absolutely crazy.
EDIT: nvm, just looked it up, you get charged one of 3 ‘bands’ (lowest is £26.80 which is what I was charged, and the highest is £319.10). I never knew it was so pricey, as I ended up having to go private after moving anyway, since nobody was taking NHS patients…
Not to detract from your point, but gender dysphoria is a medical condition. The brain undergoes sex differentiation in utero, and the rest of the body usually but doesn’t always match this.
