At this point it's worth pointing out that this user has conspicuously ignored this and other replies that point out that, beyond any moral qualms, the user is woefully uninformed about the medical rights of prisoners. Dunning-Kruger strikes again.
Here's the OJP opinion for your reference. Specifically:

I'd suggest doing some actual research into the relevant case law, e.g. Washington v Harper, instead of just googling until you find something that can be misinterpreted to support your position. While prison administrators have wide leeway to force treatment they are still required to show that it's necessary, either for safety reasons or because the treatment was mandated as part of the sentence of the inmate.
