Dave, it is my opinion that you seriously underrate the seriousness of covid-19 because you have no idea about maths or science, you are dismissive of them, as has been shown regarding climate science, the collapses on 9/11 and now a global pandemic. It’s the Dunning-Kruger effect. You have massive confidence in your own pronouncements, because you don’t even know enough to know that you’re ignorant.
Ignorance can be corrected, but arrogance is a choice.
