Yep, I looked at Out World in Data [0] at the time and from the numbers it was very clear to me that it was a disease that was mainly risky for old people and people with co-morbidities. At that point it was clear to me that most people wouldn't need to be very scared.
What about the idea that we should do every panicky thing we are told, including shun loved ones and demand people be rounded up or locked in their houses forcibly? Does that feel deeply immoral to you?
The people that just went along with it didn't know. They stuck their fingers in their ears and called the rest of us bad people. At least we know who they are now.
