Masks do work in situations where people are breathing on each other, but they have now become some sort of weird symbol of the Covid orthodoxy. I even see people alone in a car with masks, people walking in a park with masks. It's all theater.
I was watching a soccer game today. They make each team enter the field separately and line up with 6ft between players. Also bench players sit several seats from each other with masks. Then the game starts and there are 22 players grabbing each other all over the field. All safety theater, the kind that until now you only saw at the airports with the TSA nazis.
