It's also a valid point that unproven and disproven aren't equivalent. While I don't think anyone should take medical advice from political sources or for political reasons (therefore, as far as I'm aware, the well studied vaccines should be preferred to ivermectin by the vast majority of people at this time), I do think that it should be anyone's right to have full bodily autonomy and make whatever choices they want. Mainstream consensus is wrong often enough, e.g. the disastrous food pyramid that contributed to today's obesity epidemic.
I agree with the thrust of your point that the idea that there's some kind of widespread anti-Republican medical discrimination or corruption going on is silly. Just pointing out that how things currently are is not how they ought to be, and that this situation is arguably just a subset of the widely reviled War on Drugs.
