I think this is one of those issues where it's easy to spark a person's frustration.
As has been mentioned, many law-abiding transgendered persons suffer from discrimination because of their identity: having been denied insurance coverage for surgeries and drugs, suffered through employment discrimination, and been denied service or even harassed in public places. These are areas where many transgendered people feel, and rightfully so, that the government should step in to ensure they're protected equally under the law. To be aware of these injustices, and then face the possibility of a convicted murdered getting treatment that law-abiding citizens can't, is surely infuriating.
But I think that anger is really just reflective of something else, particularly the dysfunction of our health care system.
Personally, I wouldn't mind if this person had received this treatment, _if_ things like insurance coverage for drugs and surgeries for transgendered people were available to all of us.
Ironically, despite my anger, if the courts _had_ ruled in this prisoner's favor, it may have helped us in the long term. We need all the legal precedents we can get, of any size, shape, or form, which affirm the medical necessity of these treatments. That's the only way we might eventually reach a point where insurance companies as a whole provide broad coverage. That seems like the biggest legal prize which the transgender community desires at present.
