I feel we mostly have honorable providers saddled with a broken, profiteering-based system1. I feel very positive about my universal access healthcare system, in general.
3. If different doctors have different opinions, then I would look to the consensus, and the body of evidence by which they are in agreement upon.
In the US, medical consensus isn't nearly as robust a process as we might imagine.
4. Puberty blockers may not either be reversible or safe, if the latter, than any victim of malpractice has a tort claim for negligence in most civil legal systems. As for the former. That must surely be a fact that is quite obvious to the person undergoing gender transition treatments and surgical procedures.
I think in the coming years we will see an avalanche of such claims. A few have already happened. As for obviousness, I think a lot of the side effects are subtle, or slow-moving and far from obvious.
5. I have no issue with transgender rights and protections, I have every faith in people (including young people) to know what is best for themselves. I do not feel others can or should attempt to interfere in any long term decisions people make, that relate to their own bodies and minds. Unless there is very good reason. I don't see one here.
One bit of scientific consensus that's quite strong is that young people really do not have the necessary cognitive skills to imagine long-term, life changing decisions.
