“and as testing increases, and cases increase, the CFR will drop dramatically”
If the case count increases dramatically. However, you can’t calculate CFR using unresolved cases. The Deaths-to-Cases Ratio would certainly decrease with more cases found.
“I kind of get the impression that some people WANT to be proven right about the CFR being high...”
I see certain FReepers forcing others into a position that might seem that way, but it is problematic to offer false hopes (as in wishful thinking and optimistic hypotheses without substantiation) and call others out as death-cultists for not buying into them. There is a lot of criticism of FReepers by the rainbows-and-unicorns crowd.
You're right. There's also some rumor mongering - the "I heard this from a friend of a brother" sort of thing - on everything from road closures, to martial law to you-name-it - on various COVID-19 threads.
And some of the questions and skepticism for those things is not from the rainbows-and-unicorns crowd.
