Actually, the 1968 Hong Kong flu was one of the deadliest pandemics in history killing between one to four million globally. The death toll here in the U.S. was around 100k on the high end, which would be over 200k today given population adjustments. Not as serious as COVID has become ( in the U.S., though it appears it would have been worse on the global scale), but when it was ripping through society there was barely a blip about it in the media. In fact, I remember reading that a high ranking official in the Johnson administration even died from it, but there was no panic, no economic shut downs, no mask Nazis, etc. No behavior like today's Branch Covidians.
