Let me digress from the discussion of what conservatism is and why it's not good for people, and talk a little bit about the Republican party. The party doesn't actually have a platform at the moment -- as you may recall they voted to make the platform be "whatever Dear Leader says" -- but we do know that generally they stand for rich people not paying taxes, eliminating environmental, workplace safety and consumer protection regulations, not letting non-white people vote, and other stuff that probably does fit the definition of conservative.
However, they also have room for stuff that's just loony tunes. There's nothing evidently conservative about rejecting medical science, as far as I can understand. For example, that face masks are effective at preventing transmission of respiratory viruses, including Covid-19, is what is called a scientific fact, and scientific facts cannot violate any conservative principles -- they're just facts. Then there is hydroxychloroquine. Multiple high quality clinical trials from around the world have demonstrated conclusively that it is completely ineffective against Covid-19, at any stage of the disease, including for prophylaxis. That is another example of a scientific fact. I'm going to refer you to Scott Lemieux because of the NYT paywall, since he has already ripped them off:
In choosing a slate of doctors to testify about coronavirus treatments before his committee on Tuesday, Senator Ron Johnson has assembled a cast of witnesses who question much of the public health consensus about the virus.
There is a prominent vaccine skeptic, an outspoken critic of masking and social distancing, and at least two doctors who have promoted the use of an anti-parasitic drug that government scientists have recommended against using to treat the coronavirus.
It is the latest example of how Mr. Johnson, a Wisconsin Republican who has used his powerful investigative panel to amplify groundless accusations pushed by President Trump, has now embraced the role of the Senate’s leading Covid contrarian.
This shit is going to, you know, kill people. Literally. It already has. What this has to do with Ayn Rand and Edmund Burke you'll have to tell me.
Dear Dumbass: Ron Johnson is a United States Senator. Donald J. Trump is the President of the United States, who has the adoring and undying support of 95% of people who say they are Republicans. This is not cherry picking a random example of a nutcase.
