Surprise surprise, government can mobilise police/army to protect their citizens. Who would have thought. Come on, no one knew if it was a new black death or just a harmless virus. The hysteria about government taking valid steps in an unclear situation is childish.
It was also quickly made taboo to say anything comparing it to a common cold. Many platforms silenced these ideas by censoring posts and shadow banning users.
There absolutely was hystaria involved but it was leaders, medical experts, and society responding irrationally based on fear. We did know it wasn't the plague, there were some in early 2020 raising valid points that it looked to have a mortality rate closer to 0.1% largely impacting the elderly and seriously ill.
How where these steps taken by governments valid, both legally and morally, when they were driven by fear and crushing individual rights?
