There’s not one convenient monolithic intellectual bloc of…I’m not even sure what blanket term would be appropriate. COVID deniers, maybe? Except, as with that specific Tweeter, not all of them deny that COVID exists, or that it can be lethal.
There are some people that claim that COVID doesn’t exist at all, and that the whole think is a massive hoax. But there are plenty of others that accept that COVID exists, they just think it’s being overblown. For them, it’s just a slightly worse version of the seasonal flu. And and many of them even acknowledge that people die from the flu.
But, their argument goes, if we don’t shut down large sectors of the economy and mandate vaccines and masks for the flu, even in bad flu seasons, why is this flu variant so special? If (and I realize this is a fundamentally misinformed premise) COVID is only a slightly worse form of the flu, then all of the massive public health measures are unjustified. And it becomes extremely suspicious that several prominent critics of the “over-reaction” to COVID “conveniently” die of COVID within a short time period.
Which leads to speculation that they didn’t just randomly get “regular” COVID, they were targeted with a highly virulent strain. Which would be an elegant countermeasure. It both shuts them up and creates a public impression that COVID is far more prevalent, contagious, and dangerous than it “really” is.
Of course, the folks that think COVID is just a bad flu and the folks that think the whole thing is a hoax and the folks that deny the germ theory of disease somehow never seem to argue with each other, just with anyone advocating for public health measures.
It’s similar to the arguments over climate change. I’ve come across people in the same comment thread arguing: that everyone agrees that anthropogenic climate change exists, and its a straw man to claim that anyone denies it, and the actual argument is over costs and benefits of various responses; that everyone agrees climate change exists, and its a straw man to claim that anyone denies it, and the actual argument is over whether its caused by human beings; and that climate change is all a hoax. And they never responded to each other, only to anyone in the thread arguing for significant measures to combat or ameliorate climate change.
