This whole discussion and the anti-human rights bent that it has taken sickens me in so many ways.
1. Trans people, especially trans women, are incarcerated at much higher rates than the general population. This is not because trans people are "bad people"; rather, many trans people are incarcerated for committing "survival crimes" such as sex work and drug dealing, primarily because they have a hard time finding work in the legal economy due to discrimination.
2. Trans people, and again I'm talking primarily about trans women, do not have an easy time in prison, by any means. Imagine being someone who lives and identifies as a woman, who is feminine and/or appears female, who maybe even has breasts, and being placed in a men's prison. Not only do these prisoners have to conform to men's dress codes, cut their hair, shower in open facilities with men, etc., but they are easily targeted and victimized by guards and other prisoners. Sexual assault, rape, harassment all happen regularly. Sometimes trans prisoners are placed in isolation "for their own safety," but being in isolation is no picnic, either. Isolation is generally used as a severe form of punishment, so in this way, these prisoners are being punished simply for being transgender.
3. I'm not going to get into my beliefs about the prison system, but regardless of my personal views, people who are incarcerated are still people. Whether they committed a serious, violent offense (which, realistically, is the vast minority of prisoners), or a minor drug-related offense, they deserve human rights. One of those human rights is medical care. I think that most of us on this forum would agree that transition-related care is medically necessary for many transgender people. If this is true, then why should we think about this in any other way than, say, if a prisoner with a heart condition needed heart surgery? If we do think that providing transition-related care is inherently different from heart-related care, then we need to rethink our argument that transition-related care is medically necessary.
4. Yes, I think it's sucky that most trans people in the United States cannot access transition-related surgeries due to their inordinately high costs. I think that insurance plans should be required to cover transition-related care. Moreover, I think that, regardless of insurance coverage, all trans people should be able to access affordable transition-related care. To that end, I believe that arguing against the treatment of trans people in prison is a step in the WRONG direction.
