There is nothing unprecedented about COVID. It is not the deadliest pandemic by any account. We simply had different attitudes toward civil liberties and the role of government in the past. The Spanish flu saw minimal national level policy and isolated (time and space) restrictions in particular places, along with sensible policies (like outdoor classrooms) meant to ameliorate the worst aspects. The sort of coercion during COVID was unprecedented. It is not something that we should accept.
"The United States lost 675,000 people to the Spanish flu in 1918-more casualties than World War I, World War II, the Korean War and the Vietnam War combined."
0.5% of the US population died due to the Spanish Flu.
Look, I understand where you're coming from, but I don't know that you would actually prefer 1918 policies if the same scenario were to be replayed in the present day.
