I am not sure why an elective surgery for a trans individual does get priority over Prequelle's mum?
I of course would not want prisoners to lose their access to healthcare but I don't agree that "transition" surgery should be available on the NHS at all. It is not life saving or essential and in fact will involve constant hormones and drugs for the rest of the individuals life. Surgeries such as these were actually stopped at John Hopkins University, the most elite medical establishment in the USA, because research showed that 20 years later patients were MORE suicidal so it did not solve psychological conditions.
